research Effect of equilibrium pH on the structure and properties of bleach‐damaged human hair fibers
Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.
research Damage limitation: comparing the impact of polymers on bleached hair, when applied within or as post-bleach treatments
Polymers help reduce damage and improve bleached hair when used during or after bleaching.
research Research on Hair Bleach that Causes Less Hair Damage and Smells Less Pungent than Ammonium Hydroxide
AMPD is a better and less damaging alternative to ammonium hydroxide for hair bleaching.
research Impact of ultraviolet radiation‐induced damage to hair fiber integrity: A multi‐technique physicochemical characterization of surface and cortex properties
This study investigates the impact of ultraviolet (UV) radiation on hair fiber integrity, comparing it to the effects of bleaching. It simulates solar radiation damage over a Brazilian summer and finds that UV exposure causes cuticular damage similar to bleaching, with increased cystic component oxidation and decreased hydrophobicity. After 192 hours of UV exposure, hair shows significant mechanical degradation, with reduced force at 20% elongation and elongation at break, indicating more pronounced damage than chemical oxidation alone. However, the structural protein degradation from double bleaching is more severe than that from UV radiation, despite comparable enthalpy changes after 192 hours of UV exposure.
research Effects of silicone pretreatment on oxidative hair damage
Silicone pretreatment protects hair from damage and reduces color fading without interfering with bleaching or dyeing.

A 25-year-old man with hair loss from bleach damage is using oral minoxidil and considering adding Dutasteride for better regrowth and prevention. He seeks advice on Dutasteride's effectiveness and potential benefits over finasteride, and is also curious about RU58841.
community Has anyone experienced burning scalp after chemical damage (perm)?
A user experienced burning, itching, and soreness on their scalp after a perm in 2021, despite using oral finasteride, oral minoxidil, and ketoconazole shampoo. They are seeking advice on whether to pursue further medical tests or consult a neurologist for nerve pain.
community Start taking care of your skin and hair loss TODAY! I was telling myself I didn’t care, but I think the difference in my facial expression says it all. Take action asap before more permanent damage is done. I hope I can inspire some of you, because it’s so worth it. Not for others, for yourself! <3
User shared progress in treating hair loss and improving skin, using treatments like finasteride, minoxidil, RU58841, tretinoin, microneedling, and skin care regimen. Others commented on the impressive results and asked about costs and side effects.
community due to medication, age, over use of color and heat, my hair began to fall out and break. I shaved my head (35F) and I’m horrified at myself now
A woman experienced significant hair loss due to medication, hair coloring, and heat damage, leading her to shave her head and feel distressed. She is considering using wigs and possibly oral minoxidil to manage the situation while her hair regrows.
community Warning: Your Rogaine Foam Might Not Contain Minoxidil
A user experienced significant hair loss after using Rogaine foam purchased from Amazon, which failed a bleach test for Minoxidil. They discovered that even legitimate Rogaine products might be faulty and advised buying from reputable sources.
