5 / 1000+ resultsresearch Evaluation of hair fibers properties treated with acid straightener at different pH values
This study found that the acidic hair straightening formulation at pH 1.0 improved hair alignments and straightening effectiveness more than pH 2.0, but it weakened fiber strength and affected hair color and composition.

research Impact of acid (”progressive brush”) and alkaline straightening on the hair fiber: Differential effects on the cuticle and cortex properties
This study found that glyoxylic acid caused more protein loss in hair compared to traditional alkaline straighteners, though both types of treatments showed comparable effects on hair tensile strength.
research Cytotoxic Evaluation of Hair Relaxers and Straighteners Actives in Human-Derived Skin Cells
This study demonstrated that hair relaxers containing common chemicals significantly reduced cell viability and increased apoptosis in human skin cells, suggesting potential toxicity that could be assessed with advanced in vitro technologies rather than animal testing.

A 31-year-old male is using a hair loss treatment routine that includes daily 0.5mg dutasteride, 5% minoxidil, microneedling, biotin, vitamin D, omega-3 supplements, and alternating shampoos to restore hair density. He reports no side effects or noticeable regrowth yet but feels optimistic about the process.
community I cry every day, everything is very depressing
A user is experiencing hair loss despite using dutasteride and oral minoxidil, feeling hopeless and considering a hair system. They are advised to try ketoconazole, seek a second opinion from a dermatologist, and consider treatments like finasteride, RU58841, and hair transplants.
community Could the salicylic acid in my Nioxin shampoo reduce minoxidil effectiveness?
Salicylic acid in Nioxin shampoo may reduce minoxidil effectiveness by inhibiting sulfotransferase activity, potentially causing hair loss. Users suggest stopping salicylic acid use or trying alternative treatments like high-concentration tretinoin or medicated minoxidil/finasteride shampoos.
community Azelaic acid with ru58841 combination
The conversation discusses using azelaic acid to reduce scalp inflammation while using RU58841 for hair loss. It suggests applying azelaic acid in the morning and RU58841 at night to avoid degradation, while also using dutasteride and minoxidil.
community How to make Azelaic acid solution from powder?
Azelaic acid is discussed for its anti-inflammatory and anti-fungal properties, which can improve scalp health and potentially boost hair growth. It is suggested for topical use, especially alongside minoxidil.

5 / 39 results- 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.
- azelaic acid: Does it work for all types of hair loss or just DHT? One small randomised trial (26 women, no placebo) found no significant difference between 5% azelaic acid and 2% minoxidil for female pattern hair loss, which is too small to show they work equally well, and the anti-DHT rationale rests on laboratory work. For alopecia areata, telogen effluvium and seborrhoeic dermatitis there is no trial evidence for azelaic acid at all.
- What happens if I mix azelaic acid with minoxidil or regular hair loss shampoos? No published study has tested azelaic acid combined with minoxidil or with hair-loss shampoos, and layering them can irritate the scalp. Mixing anything into a minoxidil solution changes the drug in untested ways, so ask a pharmacist before combining products.
