5 / 1000+ results research Effects of Silicone Oil Viscosity on the Physical Structure and Damage Mechanisms of Hair During Permanent Wave Treatment
This study examined how different viscosities of silicone oil affect hair structure and damage during permanent wave treatments on untreated, permanent wavy, and dyed hair. Using dimethicone with viscosities of 6 cSt, 1,000 cSt, and 10,000 cSt, the researchers assessed wave efficiency, hair thickness, and tensile force. The highest wave efficiency was observed in untreated hair with low viscosity, permanent wavy hair with medium viscosity, and dyed hair with high viscosity. Hair thickness remained consistent across all groups, but tensile force, cuticle thickness, and sulfur content, which indicates hair damage, were highest with high viscosity treatments. The study concludes that silicone oil viscosity significantly impacts wave curling performance and hair damage, offering valuable insights for optimizing hair treatment formulations.

5 / 5 resultscommunity 0.5mg Dutasteride promotes more “regrowth” than 5mg oral Minoxidil
Dutasteride promotes more hair regrowth than Minoxidil. Users discuss combining treatments for better results and share personal experiences with side effects.
community Why I really believe the tension theory is the cause of MPB
The conversation discusses the tension theory as a cause of male pattern baldness (MPB), suggesting that scalp tension and reduced subcutaneous fat layer contribute to hair loss. Treatments mentioned include Minoxidil, finasteride, microneedling, scalp massages, and Botox.
community Can hard water affect your scalp/hair?
Hard water may contribute to an itchy, dry scalp and hair issues, but it doesn't affect genetic hair loss. Some users suggest using distilled water or a water softener to alleviate symptoms.
community LLLT seems like it's at least a solid maintenance tool. Can also provide ok regrowth in AA and MPB. - Pubmed
Low-Level Laser Therapy (LLLT) is seen as a safe and effective method for maintaining hair and promoting regrowth in androgenetic alopecia (AGA) and male pattern baldness (MPB), with devices like the HairMax LaserComb® and iRestore helmet being popular. Some users and professionals are skeptical about its long-term effectiveness and cost.
community Considering giving a laser comb a shot. Here’s a summary of my research on the subject.
Considering adding Low Level Laser Therapy (LLLT) to a hair loss prevention regimen; discussing the effectiveness of LLLT, and evaluating double-blind random-controlled trials that have been conducted on laser combs.
