Excess Vitamin A and topical retinoids can cause diffuse hair shedding. The user suspects their chronic telogen effluvium may be linked to using adapalene, a topical retinoid.

Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present.

Treatments mentioned include topical melatonin, Clobetasol Propionate for alopecia areata, and the lack of results from using finasteride, dutasteride, and minoxidil.

Topical dutasteride may have limited absorption due to its higher molecular mass compared to finasteride, potentially affecting its efficacy in suppressing DHT locally. Microneedling might enhance dutasteride absorption, possibly offering stronger local DHT suppression with fewer systemic effects.

A user struggles with male pattern baldness and a persistent tingling itch on their crown, trying various treatments like aloe vera, tea tree oil, and Nizoral without success. Another user suggests the itch might be psychosomatic, linked to worrying about hair loss.

A user plans to create a DIY topical treatment for hair loss using Rapamycin, possibly combined with alpha-ketoglutaric acid (a-KG). They discuss the concentration and formulation process for Rapamycin, considering safety and skin penetration, and intend to apply it every other day to the scalp.

The efficacy of degrading the androgen receptor through dermal application in DP cells, a delivery system for topical drugs that involves dissolving microneedles, and rosemary oil as an alternative anti-androgen.

Concerns about metal particles from dermapen or dermaroller needles potentially entering the skin and lymph nodes, similar to tattoo needles. Discussion includes the possibility of using Minoxidil, finasteride, and RU58841 for hair loss treatment.

The conversation discusses concerns about the potential risk of cancer from creating new hair follicles through microneedling, due to stem cell division. Specific treatments mentioned include microneedling, caffeine-containing anti-hair loss shampoos, and other unspecified topicals.

Microneedling can cause sneezing and eye tearing due to nerve stimulation, particularly near the temples and forehead. Some users find it lessens over time, while others prefer using finasteride and minoxidil for hair growth.

PP405, a topical LDH inhibitor, has shown to stimulate hair follicle stem cell proliferation in humans with moderate hair loss. They are advancing to more detailed trials this year.

The user suspects scarring alopecia and is exploring NSAIDs and turmeric/pepper for inflammation-related hair loss, having experienced burning and thinning with finasteride and testosterone reduction. They are seeking feedback while unable to afford a dermatologist.
