Carnosic acid in rosemary extract may enhance skin repair and promote hair follicle regeneration. It could be used alone or with verteporfin for scarless healing after dermal wounding.
Microneedling may enhance hair regrowth by transferring stem cells to dormant follicles, improving the effects of minoxidil. Users discuss using microneedling with needle lengths around 1.5mm to stimulate hair growth.
Hot weather can increase hair shedding, possibly due to dehydration and active sebaceous glands. Using shampoos with salicylic acid or zinc pyrithione may help; daily anti-inflammatory use is not recommended.
The user is experiencing new hair growth after using oral dutasteride, topical minoxidil, and microneedling, but is concerned about black dots on the hairline, which might be clogged pores or dormant follicles. The user previously used a topical minoxidil/finasteride spray and had good results, despite a shedding phase after switching treatments.
Dihydrotestosterone (DHT) impacts various skin conditions, including Androgenetic alopecia and seborrheic dermatitis, by causing overactivity in sebaceous glands. Topical medications Tacrolimus and Clobetasol can reduce these inflammatory conditions, and treatments like RU58841, Minoxidil, and Finasteride may also be beneficial.
