Biopolymers are increasingly used in cosmetics for their non-toxicity and skin benefits, with future biotech advancements likely to expand their applications.

The research identified key molecules that help hair matrix and dermal papilla cells communicate and influence hair growth in cashmere goats.

Using enzymes to link proteins makes hair repair treatments more effective and long-lasting.

Adding methionine to a low-protein diet helps Angora rabbits grow better fur.

The 2015 Hair Research Congress concluded that stem cells, maraviroc, and simvastatin could potentially treat Alopecia Areata, topical minoxidil, finasteride, and steroids could treat Frontal Fibrosing Alopecia, and PTGDR2 antagonists could also treat alopecia. They also found that low-level light therapy could help with hair loss, a robotic device could assist in hair extraction, and nutrition could aid hair growth. They suggested that Alopecia Areata is an inflammatory disorder, not a single disease, indicating a need for personalized treatments.

New methods can diagnose hair loss by examining the scalp and can treat it with a mix of oral and topical medications, along with cosmetic procedures like hair transplants.

Understanding hair follicle development can help treat hair loss, skin regeneration, and certain skin cancers.

Human hair is made up of different keratins, some strong and some weak, with specific types appearing at various stages of hair growth.
