Unpigmented keratinocytes absorb substances faster, while melanocytes bind more strongly to melanin.

Foxn1 is essential for hair pigmentation by directing pigment transfer to hair cells.

Radiation mainly affects keratinocyte stem cells, not melanocyte stem cells, causing hair to gray.

Scientists successfully grew mini hair follicles using human skin cells, which could help treat baldness.

Androgens can both increase and decrease hair growth in different parts of the body.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

Brain-Derived Neurotrophic Factor (BDNF) slows down hair growth and promotes hair follicle regression.

The skin has multiple layers and cells, serves as a protective barrier, helps regulate temperature, enables sensation, affects appearance, and is involved in vitamin D synthesis.

Men with baldness are more prone to skin cancers on the scalp due to sun exposure, not testosterone.

Hair follicle melanocytes die during hair regression.

Hair color is determined by melanin produced and transferred in hair follicles.

Miz1 is essential for proper hair structure and growth.

Finasteride increases hair count and improves hair growth with low risk of side effects.

Some chemicals can permanently or temporarily remove color from skin and hair, which can be distressing and is not well-regulated in cosmetics.

Androgens can cause hair growth in some areas and hair loss on the scalp.

Wnt signaling is crucial for skin development and health, and its disruption can cause skin diseases.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

Researchers created human hair follicles using a new method that could help treat hair loss.

Latanoprost can make eyelashes longer, thicker, and darker.
