Only minoxidil and finasteride are FDA-approved for hair loss, with other treatments available but less effective or with side effects.

PGD2 increases androgen receptor activity in hair cells, which could be targeted to treat hair loss.

Hair follicles can be used to quickly assess drug effects in cancer treatment.

RANKL causes lymph nodes to grow by making certain cells multiply.

Animal models are crucial for learning about hair loss and finding treatments.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

The document concludes that identifying the specific cells where skin cancers begin is important for creating better prevention, detection, and treatment methods.

Prolactin affects hair growth and skin conditions, and could be a target for new skin disease treatments.

The document concludes that understanding hair and feather regeneration can help develop new regenerative medicine strategies.

Hair follicles may soon be used more for targeted and systemic drug delivery.

The Lexington LaserComb helped regrow hair in mice with a condition similar to human hair loss.

Skin and hair can help us understand organ regeneration, especially how certain stem cells might be used to form new organs.

VEGFR-2 activation is likely involved in hair follicle growth, survival, and development.

Stem cells help remove dead cells to keep tissues healthy by balancing cell replacement and clearance.

No FDA-approved treatments for chemotherapy-induced hair loss existed in 2006; more research was needed.

Chemotherapy causes hair loss by damaging hair follicles and stem cells, with more research needed for prevention and treatment.

TAF4 is important for skin cell growth and helps prevent skin cancer in mice.

Ginsenoside Rg4 from ginseng may help hair growth by activating certain cell signals.

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

Minoxidil and finasteride treat hair loss; more research needed for other options.

Hormones during pregnancy and lactation keep skin stem cells inactive, preventing hair growth.

Certain microRNAs are important for sheep hair follicle development and could help improve wool quality.

Stem cell therapies show promise for hair regrowth in androgenetic alopecia.

Vitamin D and calcium are important for quick and effective skin wound healing.

T-regulatory cells are important for skin health and can affect hair growth and reduce skin inflammation.

Hair follicles are key to treating vitiligo and alopecia areata, but challenges exist.

Dermal stem cells help regenerate hair follicles and heal skin wounds.

Minoxidil 2% and 5% are common treatments for female pattern hair loss, with other options including anti-androgens, oral contraceptives, and hair transplantation.

The transition from growth to regression in Cashmere goat hair follicles involves changes in expression of genes related to keratin and cell differentiation.

Certain miRNAs may play a role in sheep hair follicle development, which could help improve wool production.
