We aimed to understand how retinoic acid (RA), a derivative of vitamin A, impacts hair loss, particularly in individuals suffering from androgenetic alopecia (AGA). By examining hair follicles from both the occipital and frontal areas of the scalp, we were able to conduct RNA sequencing to observe patterns relevant to HFSC (hair follicle stem cell) health.
In our experiments, we utilized a mouse model to see how administering RA affects hair growth during the telogen phase, a resting period for hair follicles. We then subjected miniaturized hair follicles to RA treatment in controlled organ cultures to assess hair shaft elongation and the activity of HFSCs.
The results revealed that RA signaling appeared to be diminished during AGA, leading to dysfunction in HFSCs. When we treated hair follicles with RA, we observed a notable recovery in hair regeneration. This treatment seemed to promote hair growth by activating HFSCs through Wnt/β-catenin signaling pathways, facilitating their transition from a quiescent to an active state.
Additionally, a clinical part of the study confirmed that RA may hold promise as an early intervention tactic in AGA, reinforcing its role in reviving hair follicle activity. Overall, our findings suggested that vitamin A can be a game-changer in addressing hair loss by effectively reactivating stem cells in hair follicles.

Severe hair loss

DO NOT TAKE THIS UNLESS YOU WANT TO LOSE YOUR HAIR. This is the worst supplement I have ever taken. The label should read "MAY CAUSE SEVERE HAIR LOSS" or it should not be sold at all. At 33, I’ve had no thinning hair, and it’s not in my family. I thought this might help my skin but after starting it, I developed a one-inch balding spot on the left side of my head, and soon after, one on the right. I discovered that extra vitamin A can cause balding, and the dermatologist advised me to stop immediately. Now I just hope my hair grows back. I am furious that this is not labelled for high risk of causing baldness.

THIS IS A TOXIC DOSE OF VITAMIN A!!! I have taken this daily since January. My hair has started thinning, which is concerning as I have thick hair and no family history of hair loss. The dose is excessive and can lead to hair loss. It's vital to know your proper intake levels to avoid this reversible cause of hair loss.

After taking vitamin E and vitamin A for 10 days, my hair stopped falling out! I was very surprised by the result! A lack of vitamin A can manifest as dry skin, brittleness, and hair loss, along with white stripes on the nails.
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 A is a fat-soluble vitamin that's essential for several critical bodily functions, including vision, immune response, and cell differentiation. It comes in two primary forms: preformed vitamin A (retinol) found in animal products like liver, fish, and dairy, and provitamin A carotenoids, primarily found in colorful fruits and vegetables such as carrots, sweet potatoes, and spinach. The body can convert carotenoids into retinol, making these plant sources a valuable dietary option, especially for those following a vegetarian or vegan lifestyle.
Aside from its role in maintaining healthy vision—particularly in low-light conditions—vitamin A plays a significant role in skin health and the functioning of the heart, lungs, and kidneys. It also supports the immune system by promoting the development and function of white blood cells. While it's uncommon to experience a deficiency in countries where a balanced diet is accessible, a lack of vitamin A can lead to serious health problems, including night blindness and increased susceptibility to infections. In contrast, excessive intake of vitamin A, particularly through supplements, can be toxic and lead to several health issues, making it crucial to maintain a balanced intake.
Vitamin A is an essential nutrient known for its significant role in various bodily functions, including vision, immune function, and skin health. While it is crucial for the maintenance of healthy skin and scalp, its effects on hair loss are more nuanced. Some studies have indicated that adequate levels of Vitamin A can promote healthy hair growth by supporting the production of sebum, an oily substance that moisturizes the scalp. This can potentially combat dry or flaky scalp conditions which may contribute to hair loss. However, it's important to note that excessive intake of Vitamin A can lead to toxicity and may actually result in hair loss, highlighting the importance of maintaining a balanced intake.
Ultimately, if you're experiencing hair loss, it's advisable to consult with a healthcare provider. They can assess your overall health and nutrition to determine if Vitamin A or any other nutrient might play a role in your specific situation. A comprehensive approach, including a well-rounded diet rich in vitamins and minerals, is typically the best way to support hair health. Remember, no single nutrient can singularly prevent or reverse hair loss, as this condition can be influenced by a range of genetic, hormonal, and environmental factors.
Based on user reviews, the timeline for seeing results from this hair loss supplement can vary, but many users report positive changes within just a few weeks to several months. For instance, one user noted noticeable improvement within a few weeks when addressing both hair loss and folliculitis Read Review. Others have shared longer-term benefits, stating that after around six months of use their hair loss had decreased significantly Read Review.
Users have experienced varying degrees of effectiveness, often linking it to the specific vitamins they were consuming in conjunction with the supplement, such as vitamin E and vitamin A Read Review.

The use of retinoic acid (RA), a derivative of vitamin A, has shown promising results in addressing hair loss, particularly in cases of androgenetic alopecia (AGA). A study conducted on hair follicles highlighted that RA can reactivate hair follicle stem cells (HFSCs), which are crucial for hair regeneration. The findings indicated that RA treatment led to an improvement in hair growth by stimulating the Wnt/β-catenin signaling pathways, thereby helping HFSCs transition from a resting state to an active growth phase [1].
Furthermore, the research suggested that RA may serve as an effective early intervention strategy in the management of AGA, potentially reversing the dysfunction that occurs in hair follicle activity during this condition. Overall, the evidence indicates that RA has significant potential as a topical treatment aimed at combatting hair loss by revitalizing the intrinsic mechanisms of hair follicle health, making it a noteworthy option for those seeking solutions in this area [1].
