Wnt ligands are crucial for hair growth and repair.

Researchers created a new mouse model for studying Citrullinemia Type I and similar conditions, showing symptoms and treatment responses like those in humans.

Noggin is necessary to start the hair growth phase in skin after birth.

Sonic hedgehog signaling is crucial for hair growth and maintaining hair follicle identity.

There are many treatments for permanent hair loss disorders, but their effectiveness varies and there's no clear best option.

Baby's toe injury linked to mom's hair loss; check baby's toes and be careful with fruit gel snacks.

DHT affects hair follicle cells by changing microRNA levels, leading to less cell growth and more cell death.

Treatment with dutasteride, minoxidil, and artificial hair transplantation improved appearance but caused folliculitis.

The document describes how to tell different types of non-scarring hair loss apart by looking at hair and scalp tissue under a microscope.

RANK-RANKL signaling is essential for hair growth and skin health.

Some treatments work for common baldness, but there's less evidence for other hair loss types, and more research is needed.

Horizontal scalp biopsy sections are better for diagnosing alopecia areata, showing fewer hair follicles and more miniaturized hairs.

Blackcurrant extract may help reduce hair loss by promoting stem cell activity in hair follicles.

Intense pulsed light treatment effectively reduces underarm hair by making hair follicles smaller and extending their resting phase.

Acne is a common skin condition linked to diet, hormones, and genetics, and early treatment can prevent scarring.

The document concludes that sex hormones are crucial for mammalian reproduction, health, and behavior, and require more research for therapeutic use.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Human skin makes sexual hormones that affect hair growth, skin health, and healing; too much can cause acne and hair loss, while treatments can manage these conditions.

The research found that specific stem cells maintain skin gland openings and that disrupting their activity can cause blockages or early cancer signs, indicating a need for targeted treatments.

Emerging therapies like stem cell and laser treatments show promise for hair regeneration.

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

Niosomes are the most effective at delivering drugs to the skin with minimal absorption into the body.

The research showed how melanocytes develop, move, and respond to UV light, and their stem cells' role in hair color and skin cancer risk.

The study concludes that regulating apoptosis could lead to new treatments for various skin and hair conditions.

N-acetylcysteine may prevent hair loss caused by chemotherapy.

Paris polyphylla saponins may effectively treat acne due to their antibacterial and anti-inflammatory properties.

Korean Red Ginseng may help protect hair from damage and promote growth.

A woman's hair loss was misdiagnosed as alopecia areata but was actually lichen planopilaris, needing immediate and ongoing treatment.

The study concluded that similar pathways regulate hair growth in dogs and mice, and these pathways are disrupted in dogs with Alopecia X, affecting stem cells and hormone metabolism.

The vitamin D receptor helps regulate skin and hair health independently of its usual vitamin D ligand.
