This study found that a cosmetic foam reduced the telogen rate in men with androgenetic alopecia, suggesting a potential benefit against male pattern hair loss.
Can stemoxydine help improve hairdensity in both men and women?Stemoxydine is a cosmetic ingredient, not an approved hair loss drug, and the manufacturer's three-month trials enrolled men only, reporting a small increase in measured hair density. One small uncontrolled study that included women reported improvement in both sexes but more in men, so a benefit for women is not established.
Does hair strand thickness decrease in men with androgenic alopecia? Can finasteride help restore it?Androgenic alopecia thins hair strands by miniaturizing follicles. The pivotal finasteride trials (1,553 men, 1 mg/day, two years) report increased hair counts and improved assessed appearance, but they measured density, not the diameter of individual strands, so the effect on thickness itself is not established.
How does cetirizine reduce inflammation linked to hair loss?Cetirizine is proposed to lower prostaglandin D2 and raise prostaglandin E2 around hair follicles; three small trials of a compounded 1% topical report modest increases in hair density and shaft thickness, with minoxidil doing better head-to-head. Topical cetirizine is off-label and unapproved for hair loss, and the evidence is too thin to call it effective or safe.
How long does it usually take to see results from latanoprost for hair growth?There is no established timeline: the only human scalp trial, a 16-man pilot, measured a hair-density increase at 24 weeks using latanoprost 0.1% — twenty times the strength of the glaucoma eye drop — and faster figures quoted elsewhere come from eyelash and animal observations. Scalp use is off-label and experimental.
NAD⁺ precursors and EGCG may increasehairdensity, but users report mixed results with no significant hair gains. Some users suggest combining these with finasteride or dutasteride for better results.
The user is experiencing excessive hair thinning and is unsure of the cause. They are seeking opinions on treatments like Minoxidil, finasteride, and RU58841.
2% fucoidan alleviated AGA symptoms, promoted hair growth, and increasedhairdensity in mice. Fucoidan is considered safe for humans as a supplement and topical skincare product, with potential therapeutic effects against AGA.
To increasehairdensity appearance, options include using hair fibers, volume powders, scalp micropigmentation, and a combination of sea salt and holding sprays. Tape-in extensions and clip-in fringes are also considered, but cost and maintenance are concerns.
The conversation discusses fluctuating hairdensity experienced over three years while using finasteride for mild male pattern baldness. The user is curious about the lack of information on this cycle of density loss and regrowth.
