5 / 875 resultscommunity Reason why placebo group got regrow on trial phase 3
Placebo hair regrowth might be influenced by propylene glycol in lotions or participants lying about using other treatments like minoxidil, finasteride, or microneedling. Being part of a study can also improve hair health due to lifestyle changes.
community RCT: Rosemary-lavender oil formulation shown to stimulate hair growth when compared to placebo (2025)
Rosemary-lavender oil can stimulate hair growth compared to a placebo. Some users combine it with treatments like dutasteride, minoxidil, and RU58841.
community Caffeine really a DHT blocker or placebo?
Caffeine is not a proven DHT blocker and does not effectively treat hair loss. Minoxidil, finasteride, and RU58841 are more reliable treatments.
community Does creatine raise DHT/ contribute to hairloss or is it purely placebo
Creatine may cause hair shedding in some individuals, but its impact on DHT and hair loss is debated. Many users report no link between creatine and hair loss, while others notice shedding despite using treatments like finasteride and minoxidil.
community Korean Laser Helmet has a 44% increase in hair growth vs 0% growth in placebo in a double-blinded randomized controlled clinical trial.
A Korean laser helmet increases hair growth by 44% compared to a placebo. Users discuss its cost-effectiveness, clinical support, and compare it to treatments like finasteride and minoxidil, focusing on wavelength and energy density.

10 / 800 results- Is rosemary oil a real treatment or just a supplement? One small trial compared rosemary oil with 2% minoxidil but had no placebo arm; the rest of the evidence comes from mice and lab work. Rosemary oil is not an established hair-loss treatment.
- Is azelaic acid a treatment on its own or does it need supplements? One small randomised trial (26 women, no placebo) found no significant difference between 5% azelaic acid and 2% minoxidil in female pattern hair loss, which is too small to show they work equally well, and the anti-DHT rationale otherwise rests on in-vitro work. Community members generally describe azelaic acid as an add-on to minoxidil or finasteride rather than a standalone treatment.
- Melatonin: Can it be combined with other treatments like minoxidil or Redensyl? No published trial has tested melatonin together with minoxidil or Redensyl, and no interaction study exists — so the combination is untested rather than shown to be safe. The melatonin scalp evidence on its own is one small placebo-controlled trial plus several uncontrolled studies.
- How does tofacitinib differ when used orally versus topically in hair loss treatment research? Oral tofacitinib acts on immune signalling throughout the body and has more published regrowth data in alopecia areata (from small studies without placebo groups), alongside an FDA boxed warning; topical tofacitinib aims to act only on the scalp, but the human evidence is a handful of small compounded-formulation studies with no large randomized trial. Neither route is approved for hair loss, and regrowth generally reverses after treatment stops.
- Are there any side effects or scalp reactions associated with white tea in hair treatments? In one trial, women using green-tea cream plus capsules reported more skin irritation than placebo; a US cosmetic safety panel judged tea-leaf ingredients safe as used only when formulated not to cause allergy.
