This study found that caffeine and flufenamic acid penetrated porcine skin more effectively through hair follicles, while the importance of the follicular pathway varied for other substances tested.
Microneedling at depths greater than 0.6 mm may damage miniaturized hair follicles, with 0.5 mm showing better results for hair regrowth. Combining microneedling with minoxidil enhances absorption, but caution is advised to avoid damaging follicles.
Using tretinoin with minoxidil may improve absorption but results vary; some users see improved follicle growth while others notice no significant difference. Applying tretinoin before minoxidil is suggested by some users.
Dutasteride reduces DHT more effectively in hair follicles than finasteride, but some individuals still experience hair loss despite treatment. Combining oral and topical finasteride may improve results, and some users experiment with topical dutasteride despite uncertainties about its absorption.
Switching from propylene glycol to glycerin in topical finasteride may reduce systemic absorption and side effects while maintaining local scalp DHT suppression. Concerns exist about glycerin's ability to deliver the full dose to hair follicles.
Clascoterone 5% topical solution shows promise for treating male-pattern hair loss by blocking DHT at the follicle without systemic absorption, potentially offering fewer side effects than oral treatments like finasteride. While results are promising, long-term safety and effectiveness need further study, and it may serve as a starting point for developing more effective treatments.
Why is Vitamin C important for hair and hair follicles?Vitamin C is needed for collagen synthesis, antioxidant defense and iron absorption, all of which matter for hair follicles. Extra vitamin C has not been shown to improve hair in people who are not deficient.
