Advanced therapies like gene, cell, and tissue engineering show promise for hair regrowth in alopecia, but their safety and effectiveness need more verification.

Topical treatments can deliver active molecules to skin stem cells, potentially helping treat skin and hair disorders, including skin cancers and hair loss.

Non-immune dermal cells dominate, epidermal cells increase after day 9, and certain immune cells persist beyond inflammation in wound-induced hair follicle regeneration.

After skin injury, adult mice can grow new hair follicles, and this process can be increased or stopped by manipulating Wnt signals.

The conclusion is that understanding how hair follicle stem cells live or die is important for maintaining healthy tissue and repairing injuries, and could help treat hair loss, but there are still challenges to overcome.

Hair loss from alopecia areata and androgenetic alopecia can be treated, but more effective and safer treatments are needed.

Tissue from dog stem cells helped grow hair in mice.

PAI-2 helps in the maturation and protection of hair and nail cells.

Stress can cause early aging in certain skin cells, leading to problems with hair growth.

Certain cells outside the hair follicle's bulge area can quickly regenerate damaged hair follicles, potentially helping to reduce hair loss from cancer treatments.

A protein called sFRP4 from skin cells stops the development of pigment-producing cells in hair.

A protein called FGF9 helps regenerate hair follicles in mice after skin damage, and increasing FGF9 could potentially help human hair growth.

Hair follicle stem cells are key for hair and skin regeneration, can be reprogrammed, and have potential therapeutic uses, but also carry a risk of cancer.

Immune cells around hair follicles help control hair growth and could be targets for treating hair disorders.

The gel with icariin speeds up wound healing, reduces scarring, and helps hair growth by controlling BMP4 signaling. It also reduces inflammation and improves wound quality in mice, adapts to different wound shapes, and gradually releases icariin to aid healing. It also prevents too much collagen and myofibroblast formation during skin healing.

Laser treatment and synovial fluid can change hair follicle cells to resemble joint cells, with the changes being more significant when both treatments are used together.

Skin fat has important roles in hair growth, skin repair, immune defense, and aging, and could be targeted for skin and hair treatments.

Nanofiber structure helps regenerate hair follicles.

Thymosin β4 helps increase hair growth in Cashmere goats.

Light therapy might help treat hereditary hair loss by improving hair follicle growth in lab cultures.

Stem cells from whiskers can be transplanted to stimulate hair growth.

LGR5 is a common marker of hair follicle stem cells in different animals and is important for hair growth and regeneration.

Fat tissue under the skin affects hair growth and aging; reducing its inflammation may help treat hair loss.

Different stem cells are key for hair growth and health, and understanding their regulation could help treat hair loss.

Mice can regrow hair on wounds due to specific cell interactions and mechanical forces not seen in rats.

The new baby shampoo and wash with stearic acid is safe and potentially effective for nourishing babies' skin.

Improving the environment and cell interactions is key for creating human hair in the lab.

Using the drugs AMD3100 and Tacrolimus together greatly improves skin healing and hair growth after a deep skin cut by increasing stem cells in the wound.

Overactivating Hedgehog signaling makes hair follicle cells in mice grow hair faster and create more follicles.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.
