In this study, the researchers reported extensive gene loss and high pseudogenization rates of α-keratin genes in cetaceans compared to terrestrial mammals, likely linked to hair loss and aquatic adaptations.

This study investigated the hair structure of wild pigs in the Balıkesir region using stereomicroscopy and scanning electron microscopy, finding distinct bifurcation patterns, but concluded that pig bristles used in brushes likely wouldn't retain these features, complicating species identification.

This study observed that particles sized 300-600 nm penetrate hair follicles more efficiently, likely due to alignment with the thickness of the human hair cuticula.
A user with medium length hair and thinning at the top is using an adenosine-based hair growth serum and seeking advice on whether to use a boar bristle or nylon bristle brush to stimulate hair growth. They are concerned about their sensitive scalp.
The user experienced initial hair improvement with dutasteride and minoxidil but saw worsening at seven months, likely due to shedding. The consensus is to continue treatment, as shedding is common and improvement may take up to a year.
The conversation is about finding a suitable hairbrush for diffuse thinning hair without causing separation or flattening. The user is using oral dutasteride, minoxidil foam, Nizoral, microneedling, and Pura D’or shampoo and conditioner.
Using a silicone scalp massager may cause hair shedding, but it could also stimulate blood flow and help with scalp conditions. Finasteride and minoxidil are used to manage hair loss, with mixed results on regrowth and maintenance.
PP405 targets hair follicle stem cells differently than exercise-induced lactate, suggesting exercise alone may not replicate its benefits. Minoxidil and finasteride are recommended alongside exercise for hair regrowth, with additional suggestions like spicy food and infrared exposure.
Surgery that moves hair follicles from the back of the scalp to thinning areas
Is a hair transplant painful?Clinics say local anaesthetic makes the procedure itself mostly comfortable, but the anaesthetic injections sting and soreness for a few days afterwards is common. Pain varies from person to person.
Is a hair transplant permanent?Transplanted hair usually lasts long term, but it is not guaranteed and the hair around it can keep thinning, so the overall result can change with time.
