Folic acid shows limited protective effects
In vivo assay of the ethanol-induced embryonic hair cell loss and the protective role of the retinoic and folic acid in zebrafish larvae (Danio rerio).
Combined treatment yields positive results.
We explored the effects of folic acid on hair loss in zebrafish larvae after exposure to different concentrations of ethanol. This study revealed how gestational ethanol exposure can harm the development of sensory hair cells. We found that even small amounts of ethanol lead to a significant decrease in hair cell count.

When we co-treated the larvae with folic acid while still exposing them to ethanol, we noted a modest increase in the number of hair cells compared to those that only received ethanol. However, despite these benefits, the hair cell counts after folic acid treatment were still significantly lower than those of the control group that did not receive any ethanol or treatment.

Unfortunately, despite folic acid showing some protective effects, the results suggest it may not be enough on its own to fully prevent hair cell loss induced by ethanol. Thus, while folic acid can have a positive influence, its isolated impact on hair loss is not entirely clear due to concurrent ethanol exposure in this study. Therefore, we conclude that while folic acid does offer some benefit, more effective protection against hair cell loss may come from other treatments, such as retinoic acid.

Folate's role in hair growth unclear
L-Cystine-Containing Hair-Growth Formulation Supports Protection, Viability, and Proliferation of Keratinocytes.
Limited specific effect on hair loss
We investigated the effects of folate within a well-structured study that examined its role in hair loss treatments. Although part of a marketed oral combination for diffuse hair loss, folate's specific impact was challenging to isolate because it was evaluated alongside other compounds.

Our research utilized a minimal growth culture system to mimic the decreased activity of human hair follicular keratinocytes. We compared these cells cultured with and without four key compounds of the treatment, including folate. Our findings indicated that while the overall combination improved cell metabolism and proliferation, we couldn't clearly assess folate's individual contribution to preventing hair loss.

Ultimately, this approach revealed that L-cystine was more prominently linked to protective effects against oxidative stress, overshadowing any potential benefits from folate alone. As a result, we conclude that folate's direct effectiveness for hair growth remains ambiguous within this specific formulation and context.

Significant improvement
I have been suffering from hair loss since adulthood, and it has worsened recently. However, after taking vitamin C and D for two weeks, I noticed a significant improvement.

Hair loss stopped
I took it for my hair, and I genuinely noticed that my hair loss stopped. It’s very beneficial, easy on the stomach, and comes with no side effects. One daily pill is a reasonable amount.

Stopped hair loss
Due to my anemia, I was advised to take vitamin B9 with my iron supplement to enhance red blood cell production and iron absorption. Along with addressing my health issues, this supplement has also stopped my hair loss.

Effective B12
To combat hair loss, I was taking vitamin B12, which worked effectively. My hair stopped falling out, and my nails became stronger, with easy-to-swallow, odourless capsules.

No hair loss
I started taking them right after childbirth, along with selenium, zinc, and iron. Remarkably, there was no hair loss; everything is fine.
