Male pattern baldness may be caused by factors like poor blood circulation, scalp tension, stress, and hormonal imbalances, but the exact causes are still unclear.

Combining physical dermabrasion with chemical peeling is more effective for skin treatment than chemical peeling alone.

Melatonin in the skin helps protect against damage from stress and UV rays, and could be used to treat certain skin conditions.

Hemp-derived cannabinoids can benefit skin and hair without causing a high.

Gray hair can potentially be reversed, leading to new treatments.

Hair follicles on the scalp interact with and respond to the nervous system, influencing their own behavior and growth.

Skin and hair renewal is maintained by both fast and slow cycling stem cells, with hair regrowth primarily driven by specific stem cells in the hair follicle bulge. These cells can also help heal wounds and potentially treat hair loss.

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.

Improved understanding of stem cell mechanisms can enhance skin tissue engineering.

Microneedle technology has advanced for painless drug delivery and sensitive detection but faces a gap between experimental use and clinical needs.

Different types of stem cells in hair follicles play unique roles in wound healing and hair growth, with some stem cells not originating from existing hair follicles but from non-hair follicle cells. WNT signaling and the Lhx2 factor are key in creating new hair follicles.

Burn scars heal abnormally and more research is needed to find better treatments.

CBD can either reduce inflammation and not affect hair growth at low levels or inhibit hair growth at high levels.

Targeting the skin's endocannabinoid system could help treat skin disorders.

RANKL improves the immune response against herpes simplex virus by enhancing T cell activation and could help develop better treatments or vaccines.

Beard hair can be used for hair transplants in severe alopecia cases, with minimal complications and good results.

Sensitive skin often causes discomfort, affects many people, especially women and older adults, and should be managed with careful product selection.

Stress increases certain chemicals in the skin and nerves, which might worsen skin conditions.

A compound named ZCZ90 can increase muscle spindle firing, potentially helping treat muscle spasms and hypertension.

Neuropathic pruritus is a commonly overlooked and wrongly diagnosed type of chronic itching that is hard to treat.

Different types of hairs on a rat's hindlimb have varying levels and patterns of nerve innervation.

Sensory neuron and Merkel cell changes in the skin happen independently during normal skin maintenance.

Merkel cells stabilize nerve endings in the skin, and they change independently of each other.

The skin is vital for protection, temperature control, fluid balance, immunity, and sensing, with damage affecting daily life and mental health.

New methods for skin and nerve regeneration can improve healing and feeling after burns.

Rat vibrissae have sensory terminals with specific structures that help detect hair movements.

Nerve signals are crucial for hair follicle stem cells to become skin stem cells and help in wound healing.

Sensory neuron and Merkel-cell changes in the skin happen independently during normal skin maintenance.

Hair follicle stem cells are crucial for touch sensation and proper nerve structure in mice.

Dynamic, light touch is sensed through a common mechanism involving Piezo2 channels in sensory axons.
