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.

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.

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.

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.

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.

Effective combination
An outstanding blend of vital elements in one capsule! A significant portion of the population suffers from vitamin D deficiency. I consulted my doctor regarding my hair loss and discovered my vitamin D was low at 30. After a month of supplementation, my levels rose to 46, necessitating an increased dosage, hence I added vitamin K. I was thrilled to find this perfect combination in just one capsule, as per my endocrinologist's advice! I highly recommend it!

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.

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.
