5 / 1000+ results research Sequence analyses of Type I and Type II chains in human hair and epithelial keratin intermediate filaments: Promiscuous obligate heterodimers, Type II template for molecule formation and a rationale for heterodimer formation
Type I and Type II keratin chains can form heterodimers despite sequence differences.
research In vivo formation steps of the hard α-keratin intermediate filament along a hair follicle: Evidence for structural polymorphism
Hair follicles form hard α-keratin filaments in four steps, showing structural differences.
research De novo filament formation by human hair keratins K85 and K35 follows a filament development pattern distinct from cytokeratin filament networks
In this study, transfection experiments showed that mutations in the K85 gene affect filament formation with K35, which may impact hair formation related to ectodermal dysplasia.
research Suprabasal change and subsequent formation of disulfide-stabilized homo- and hetero-dimers of keratins during esophageal epithelial differentiation
In this study, rabbit esophageal epithelial cells were found to produce K4 and K13 keratins in suprabasal cells, forming disulfide-crosslinked dimers that may support the physical stability of the esophageal lining.

5 / 142 resultscommunity Additional supplements / peptides to maximize finasteride benefit
The user is using finasteride, HGH, GHK-CU, BPC-157, KPV, biotin/collagen/keratin vitamins, ketoconazole shampoo, and low-dose naltrexone to address hair loss, avoiding minoxidil due to past shedding experiences. Adenosine is discussed as a potential alternative to minoxidil, though it is noted to be expensive and hard to find.
community Should I get transplant #4 or just shave my head?
A 36-year-old considering a fourth hair transplant is advised to either shave his head or use a hair system due to poor results from previous transplants and late medication use. He plans to consult top surgeons and adjust his current treatments, including finasteride and minoxidil.
community Bryan (the guy who reversed aging) shares treatment that reversed his hair loss
A person improved hair loss from Norwood 3 to Norwood 2 using a topical formula with minoxidil, dutasteride, and tretinoin, plus oral minoxidil and red light therapy. There is skepticism about the treatment's effectiveness and concerns about misleading comparison photos.
community What is the options after unsuccessful dut+minox 2x a day?
The user has been experiencing aggressive hair loss despite using finasteride, minoxidil, dutasteride, ketoconazole, and derma rolling. Suggestions include continuing current treatments, considering RU58841, checking for deficiencies, and possibly trying collagen supplements or oral minoxidil.
community Minoxidil and seborrheic dermatitis
Minoxidil use may worsen seborrheic dermatitis, causing itching and dandruff. Users consider stopping minoxidil or switching to foam to improve scalp condition.

4 / 801 results- What role does keratin play in strengthening weak or thinning hair? Keratin strengthens hair by forming protective structures that prevent breakage and thinning.
- Are keratin treatments good for people with alopecia, or do they only improve the hair’s appearance? Keratin treatments improve hair appearance but do not address alopecia or stimulate growth.
- Is keratin in shampoos and conditioners actually absorbed by the hair, or does it just coat the surface? Keratin in shampoos mainly coats the hair rather than being absorbed.
