Hair growth and development are controlled by specific signaling pathways.

DHT in the human prostate is produced through multiple pathways, not just from testosterone.

As people age, their hair follicles produce less pigment, leading to gray and white hair, due to factors like reduced enzyme activity and damage to melanocyte DNA.

Laser hair removal effectiveness depends on targeting hair structures without harming the skin, and improvements require more research and expert collaboration.

Lupus affects the body and skin, causing joint pain and skin issues that can be treated with steroids and antimalarial drugs.

In-office laser hair removal works well long-term, especially Nd:YAG for darker skin, but home devices need more testing.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

A gluten-free diet significantly improves skin and health issues in people with dermatitis herpetiformis, a skin condition linked to celiac disease.

Understanding how cells die in the skin is important for treating skin diseases and preventing hair loss.

Platelet-rich plasma might help with hair growth and skin conditions, but more research is needed to prove its effectiveness and safety.
