Mimicking fetal wound environments may enable scarless healing in adults.

Modifying certain signals in the body can help wounds heal without scars and regrow hair.

Horse skin has a layered epidermis, a dermis with hair follicles, sweat and sebaceous glands, and is supplied by small arteries.

Epithelial-mesenchymal interactions control hair growth cycles through specific molecular signals.

Understanding hair growth involves complex interactions between molecules and could help treat hair disorders.

Skin aging is due to impaired stem cell mobilization or fewer responsive stem cells.

A long-acting Vitamin C derivative helps hair grow by stimulating cells and increasing growth factors.

Follicular Cell Implantation might become a new treatment for hair loss and could lead to advances in organ regeneration.

Melatonin receptors in hair follicles help regulate hair growth and could treat hair loss.
