This study dives into how 1,25-(OH)D, a potent form of vitamin D, influences hair growth. Through a combination of experiments in live mice, hair follicle organ culture, and detailed cellular investigations, we uncovered that this vitamin enhances hair regeneration.
Specifically, we found that 1,25-(OH)D not only extends the growth phase of hair follicles but also improves the abilities of certain skin cells that are vital for hair growth. This process relies on receptors for vitamin D, highlighting the importance of our body’s biological pathways in managing hair health.
Interestingly, our findings showed that 1,25-(OH)D can also negate some of the negative effects of DHT—a hormone often linked to hair loss. Overall, this suggests that vitamin D3 could be an effective treatment option for those experiencing androgenetic alopecia, or common hair loss.

Vitamin D3 improves hair regrowth
Efficacy of Oral Vitamin D Therapy in Patients Suffering from Diffuse Hair Loss (Telogen Effluvium).
We explored the prevalence of diffuse hair loss, specifically telogen effluvium (TE), and the effectiveness of oral vitamin D therapy in treating this issue among women in southern Punjab, Pakistan. Our study involved 40 adult women who received 200,000 IU of vitamin D every two weeks for three months.
After treatment, we assessed the participants' hair growth condition 15 days following their last dose. We found that the average age of the women was 32.2 years, with the age group of 21-30 exhibiting a higher prevalence of TE than those aged 31-40.
Remarkably, 82.5% of the women experienced significant improvement in hair growth after the treatment. We observed that younger women who do not use sunscreen but often consume milk or milk protein showed particularly notable results. This suggests that vitamin D could be a promising option for those struggling with hair loss due to TE.

Vitamin D3 may aid hair growth
Trichotillomania associated with a 25-hydroxy vitamin D deficiency: A case report.
We observed how vitamin D3 may influence hair loss in individuals suffering from trichotillomania, a condition characterized by the compulsive urge to pull out hair. The study focused on two female patients who were experiencing noticeable hair loss on their scalps, assessed using the Massachusetts General Hospital Hair Pulling Scale.
To promote hair growth, both patients were given dietary supplementation of vitamin D3 at a dose of 1000 IU daily. Over a treatment period of 3 to 4 months, we noted significant improvements in both patients. This was evidenced by a reduction in hair loss linked to their obsessive-compulsive disorder, which corresponded with increases in their serum 25-hydroxyvitamin D levels.
The results suggest there's a potential connection between vitamin D deficiency and trichotillomania, particularly how inadequate vitamin D may exacerbate hair loss in those susceptible to this disorder. Overall, we found support in both experimental and clinical evidence for the role vitamin D may play in hair loss associated with trichotillomania.

Vitamin D shows promise for hair loss
Treatment of alopecia totalis/universalis/focalis with vitamin D and analogs: Three case reports and a literature review.
We explored the potential of vitamin D3, particularly its active form calcitriol, in treating various types of hair loss, including alopecia totalis, universalis, and focalis. Our focus was on three young girls who had battled with severe hair loss for extended periods without success in previous treatments.
Over the course of the study, we initiated a regimen that started with a six-month course of vitamin D3 repletion using oral cholecalciferol, which did not yield immediate results. However, upon switching to calcitriol and its analog, paricalcitol, two out of the three girls experienced significant hair regrowth. One girl saw hair begin to regrow within six months, and her progress stabilized over the next four years with increased doses.
The second patient faced some side effects, such as mild hypercalcemia when taking calcitriol, which we successfully managed by transitioning to paricalcitol. Meanwhile, our third patient experienced a rapid resolution of hair loss with a high dose of cholecalciferol. These findings suggest that vitamin D may hold promise as a therapeutic option in managing specific types of alopecia, warranting further study in larger clinical trials.

Microneedling with Vitamin D3 is effective
Combined microneedling with topical vitamin D3 or bimatoprost versus microneedling alone in the treatment of alopecia areata: A comparative randomized trial.
We explored the effectiveness of vitamin D3 in treating alopecia areata (AA), a condition that leads to hair loss. To do this, we conducted a study with 75 participants, dividing them into three groups. One group received microneedling treatment alone, while the other two groups received microneedling combined with either topical vitamin D3 or bimatoprost, a drug known to promote hair growth.
Throughout the study, we measured participants' progress using clinical evaluations and a scoring system to gauge hair regrowth. Interestingly, both the vitamin D3 and bimatoprost groups showed significant improvements in hair regrowth compared to the microneedling-only group. However, after three months, we found no notable difference between the regrowth achieved with vitamin D3 and that with bimatoprost.
Importantly, all treatments were well tolerated, with only mild and temporary side effects reported. This leads us to conclude that while vitamin D3 in combination with microneedling offers a promising approach for localized AA, its benefits may not be significantly greater than those of bimatoprost.
After four months of using the medication, my evaluation is quite positive. I took a pill once every two weeks, and my tests revealed excellent vitamin D levels. I experienced 100% hair loss initially, but this has now decreased by 50%. Furthermore, my joint pain has disappeared, and my memory issues no longer exist.

Stopped hair loss
This product was very helpful for my vitamin D deficiency, which stopped my hair loss. I was literally bald before.
Hair loss, also known as alopecia, is a common condition that affects both men and women, characterized by the thinning or complete loss of hair from the scalp or other areas of the body. It can occur due to various factors, including genetics, hormonal changes, medical conditions, and environmental factors. The most prevalent type of hair loss is androgenetic alopecia, often referred to as male or female pattern baldness, which typically results in a receding hairline or thinning crown in men and overall thinning in women.
In addition to genetic predisposition, hair loss can be triggered by stress, poor diet, certain medications, and underlying health issues such as thyroid disorders or autoimmune diseases. There are various treatment options available, ranging from over-the-counter products like minoxidil to prescription medications and hair restoration procedures, depending on the severity and cause of hair loss. It's crucial to consult with a healthcare professional to determine the most appropriate treatment plan tailored to individual needs and conditions.
Vitamin D is a fat-soluble vitamin that's essential for maintaining healthy bones and teeth, supporting immune system function, and facilitating normal cell growth and development. It plays a crucial role in calcium absorption in the gut, which is vital for bone health. Unlike most vitamins, our bodies can produce Vitamin D when exposed to sunlight, specifically UVB rays, which is why it’s often referred to as the "sunshine vitamin." However, depending on your geographical location, lifestyle, and skin type, getting sufficient Vitamin D from the sun alone can be challenging, particularly during the winter months.
In addition to sunlight, Vitamin D can be obtained from certain foods such as fatty fish (like salmon and mackerel), fish liver oils, and fortified foods like milk and cereals. Some individuals may also consider supplements, especially if they're at risk for deficiency. Insufficient vitamin D levels are linked to various health issues, including rickets in children, osteomalacia in adults, and even an increased risk of chronic diseases. Regularly checking your vitamin D levels and consulting with a healthcare professional can help ensure you're meeting your needs for optimal health.
Vitamin D plays a critical role in various bodily functions, including the health of hair follicles. Research has indicated that a deficiency in vitamin D may contribute to hair loss, particularly in conditions such as alopecia areata. Vitamin D receptors are found in hair follicles, suggesting that adequate levels of this vitamin can promote healthy hair growth. Supplementing with vitamin D might help those who are deficient and experiencing hair loss, but it’s essential to combine this with a balanced diet and other hair care practices for the best results.
However, while some studies suggest a link between vitamin D and hair health, evidence is still emerging, and further research is necessary to establish a definitive connection. It's crucial to consult with a healthcare provider before starting any supplementation, as they can assess your individual needs and ensure that you’re not exceeding recommended levels, which can have adverse effects. For those looking to improve hair health, focusing on a holistic approach that includes a proper diet, regular exercise, and possibly, vitamin D supplementation, could be more effective than relying solely on one nutrient.
Based on user reviews of this vitamin D supplement, it typically takes anywhere from a few weeks to several months to see noticeable results in hair loss. Many users report improvements starting as early as two weeks into their regimen Read Review. However, others suggest that significant changes may become apparent after one to three months of consistent use Read Review, Read Review.
For instance, several users have noted reductions in hair loss within three weeks and a marked improvement in their hair quality after about two months Read Review, Read Review.

Several scientific studies support the use of vitamin D3 as a potential treatment for hair loss, particularly in various alopecia conditions. One significant study found that a vast majority (79.17%) of patients experiencing diffuse hair loss were deficient in vitamin D3, suggesting a strong correlation between low levels of this vitamin and hair loss [1]. Another study highlighted the effectiveness of intralesional vitamin D3 injections in treating patchy alopecia areata, where it was noted that patients reported greater satisfaction and fewer adverse effects compared to traditional treatments [2].
Additionally, experimental research indicates that vitamin D3 can enhance hair growth by prolonging the hair follicle growth phase and improving skin cell function essential for hair health [3]. Furthermore, vitamin D3 was identified as beneficial for patients suffering from trichotillomania, where dietary supplementation of vitamin D3 led to significant improvements in hair growth [8]. Collectively, these findings suggest that vitamin D3 holds promise as a supportive treatment option for various hair loss conditions, although further research is necessary to confirm its standalone efficacy.
Based on user reviews, many individuals have reported significant improvements in their symptoms after using this vitamin D supplement. For instance, one user noted that their hair loss decreased by 50% after four months of use, alongside the disappearance of joint pain and memory issues Read Review. Others have highlighted that they experienced a reduction in fatigue and an overall boost in mood and energy levels, with improvements occurring as quickly as one week into their regimen Read Review.
Numerous users specifically mentioned the product's efficacy in combating hair loss due to vitamin D deficiency, with one user stating they no longer experienced hair loss after starting the supplement Read Review. Moreover, a review noted that after just one week, hair loss was noticeably reduced Read Review. While individual results can vary widely, the consensus among users indicates that consistent use of this vitamin D supplement can lead to beneficial effects both in alleviating hair loss and improving overall health.
Based on user reviews, there seems to be a positive consensus regarding the combination of this vitamin D supplement with other supplements for handling hair loss. Users report significant reductions in hair loss when used alongside other treatments aimed at alleviating deficiencies. For instance, one user noted a 50% decrease in hair loss after four months, emphasizing that this supplement enhanced their vitamin D levels considerably Read Review.

Furthermore, several reviews highlight that users experienced compounded benefits when combining this vitamin D with other health improvements such as joint pain relief and fatigue reduction, underscoring its multifaceted approach to addressing deficiency-related symptoms Read Review. A user mentioned that after taking the supplement, they observed a halt in hair loss and an improvement in their hair’s appearance Read Review. Overall, many users appreciate that this vitamin D supplement enhances other treatments they may be using, leading to a holistic improvement in their health and hair condition.
The optimal dose of Vitamin D for treating hair loss varies depending on the individual's condition and the treatment method used. In a study focusing on diffuse hair loss (telogen effluvium), participants were administered 200,000 IU of Vitamin D every two weeks for three months. Remarkably, 82.5% of these women experienced significant improvement in hair growth during this period [1]. This suggests that high doses of Vitamin D can effectively aid in hair regrowth for specific types of hair loss.
For those dealing with conditions like alopecia areata, intralesional Vitamin D3 injections were explored and found to be effective, though no specific dosage was declared superior compared to triamcinolone acetonide [2]. Other research using dietary supplementation of 1000 IU Vitamin D3 daily showed promising results in improving hair growth among patients with trichotillomania within three to four months [8]. Although these findings highlight various approaches, they also underscore the necessity for personalized treatment plans since individual responses and conditions can significantly alter the effectiveness of Vitamin D in treating hair loss.

Vitamin D3 linked to hair loss
Filling the Gaps: Vitamin D Status in Diffuse Hair Fall Among Pakistanis.
We explored the relationship between vitamin D3 levels and diffuse hair loss among a sample of 120 patients in a dermatology clinic. Participants, both male and female, reported losing over 100 strands of hair daily and observed positive results from a hair pull test.
Through our analysis, we found that a staggering 79.17% of these individuals were vitamin D3 deficient. The average vitamin D3 level among the patients was just 17.33 ng/ml. Most of the patients were under 30 years old, indicating that this issue may affect younger adults significantly.
Interestingly, vitamin D3 deficiency was particularly noted in various types of hair loss, including female and male pattern hair loss, diffuse alopecia areata, and telogen effluvium.
This study emphasizes the importance of recognizing and treating vitamin D3 deficiency, especially in patients experiencing diffuse hair fall. By addressing these nutritional gaps, we may offer a viable pathway to help reduce hair loss in affected individuals.

Assessing vitamin D3 for hair loss
Intralesional vitamin D3 versus intralesional triamcinolone acetonoid in patchy alopecia areata: a comparative clinical and dermoscopic study.
We explored the effectiveness of intralesional vitamin D3 as a treatment for patchy alopecia areata (AA). This study involved 40 adult participants divided into two groups: one group received vitamin D3 injections, while the other received triamcinolone acetonide injections, both administered every four weeks for up to three sessions.
Our observations included clinical and trichoscopic evaluations at the start of treatment, after each injection, and three months following the treatment sessions. While both treatments showed a significant reduction in AA-specific trichoscopic signs, there was no statistically significant difference in the overall improvement between the two groups.
Interestingly, while both treatments were similarly effective, patients reported fewer adverse effects and greater satisfaction with the vitamin D3 injections. This points to the potential of vitamin D3 as a simpler, safer, and cost-effective option for patients dealing with patchy hair loss. Overall, our findings suggest that intralesional vitamin D3 could indeed be a promising alternative in treating alopecia areata.
