Skin stem cells are crucial for maintaining and repairing the skin and hair, using a complex mix of signals to do so.

Hair usually grows back 1-3 months after treatment for anagen effluvium, and children with Loose Anagen Hair Syndrome often improve by adolescence.

The conclusion is that skin and hair patterns are formed by a mix of cell activities, molecular signals, and environmental factors.

Chemotherapy and radiotherapy can cause skin side effects like rashes, hair loss, and nail changes, which are usually managed with conservative treatments.

Different women's hair and skin glands respond to hormones in varied ways, which can cause unwanted hair growth even with normal hormone levels, and more research is needed to treat this effectively.

Use 5% minoxidil or oral finasteride for mild-to-moderate hair loss, combine with hair transplant for severe cases.

Alopecia areata is a hair loss condition caused by immune factors and can be treated with JAK inhibitors.

Minoxidil effectively treats hair loss, especially androgenetic alopecia, but needs more research for better understanding.

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

Metformin helps improve skin regeneration by increasing the growth of skin stem cells.

Hair is important for protection, social interaction, and temperature control, and is made of a growth cycle-influenced follicle and a complex shaft.

Chemotherapy affects blood vessels in hair follicles, not stem cells, allowing hair regrowth.

Different fields of expertise must work together to better understand hair growth and create effective hair loss treatments.

Cryopreserved mouse whisker follicles can grow hair when transplanted into nude mice.

Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.

P-cadherin is crucial for hair follicle pigmentation but not skin pigmentation.

Keratosis pilaris is often linked to genetic mutations and causes skin and hair abnormalities, regardless of those mutations.

Multi-omics techniques help understand the molecular causes of androgenetic alopecia.

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

Human hair has a protective lipid layer that can be damaged by moisture and treatments, affecting hair growth and health.

Hair greying is linked to reduced ATM protein in hair cells, which protects against stress and damage.

Transplanted hair follicles show significant changes after FUE, needing more research.

The reconstructed skin model from hair follicles functions like human skin in processing chemicals and can be used to test ingredient safety.

Phaeodactylum tricornutum extract helps hair follicle cells grow by activating the ERK1/2 pathway.

Dexpanthenol helps human hair follicle cells grow by preventing aging and death, and by supporting growth signals.

The hair follicle's connective tissue is a key source of a certain collagen in human scalp skin.

Caffeine applied to the scalp can protect hair follicles from UV damage.

Hair can't be reliably repaired once damaged; prevention and proper product use are key to maintaining hair health.

Cosmetic procedures can harm hair, but damage can be minimized with knowledge and care; however, once hair is damaged, it cannot be reliably repaired.

Scalp cooling to prevent hair loss from chemotherapy works for some but not all, and studying hair damage markers could improve prevention and treatment.
