The research found that people's hair proteins vary, especially by ethnicity and body part, which could help identify individuals in forensic science.

The research found that people's hair proteins vary by individual and body part, with some differences between ethnic groups, which could help in forensics.

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.

The document concluded that stem cells are crucial for skin repair, regeneration, and may help in developing advanced skin substitutes.

Skin problems in the elderly are unique and may indicate other diseases, involving changes in skin, hair, nails, and increased cancer risk.

Hair follicle development is controlled by interactions between skin tissues and specific molecular signals.

Human skin can make serotonin and melatonin, which help protect and maintain it.

Growing human skin cells in a 3D environment can stimulate new hair growth.

Melatonin may benefit skin health and could be a promising treatment in dermatology.

The peptide GHK-Cu helps heal and remodel tissue, improves skin and hair health, and has potential for treating age-related inflammatory diseases.

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.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

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.

Normal skin cell renewal doesn't need RAR signaling, but vitamin A-related skin thickening does.

Hormones significantly affect hair and oil gland function in the skin, and more research is needed on skin-related hormone disorders.

Melanocytes are crucial for skin pigmentation and can affect conditions like melanoma, vitiligo, and albinism, as well as hair color and hearing.

Mutations in Gasdermin A3 cause skin inflammation and hair loss by disrupting mitochondria.

Mushrooms have beneficial properties for skin and hair care products and have great potential for future cosmetic use.

Short-chain fatty acids from *Cutibacterium acnes* cause skin inflammation, contributing to acne.

Skin problems are very common in people with end-stage kidney disease.

Epidermal stem cells could lead to new treatments for skin and hair disorders.

The study showed that hair follicle stem cells can maintain and organize themselves in a lab setting, keeping their ability to renew and form hair and skin.

Fat from the body can help improve hair growth and scars when used in skin treatments.

Nanocarrier-loaded gels improve drug delivery for cancer, skin conditions, and hair loss.

Adult mice can grow new hair from skin wounds.

Skin tumor regression is helped by retinoic acid signaling blocking Wnt signaling.

Prolactin may play a significant role in skin and hair health and could be a target for treating skin and hair disorders.

The document explains hair growth and shedding, factors affecting it, and methods to evaluate hair loss, emphasizing the importance of skin biopsy for diagnosis.

Hair analysis for drugs needs a better understanding of how drugs enter hair, considering factors like hair structure and pigmentation.

Dendrobium officinale polysaccharides may help with hair growth, skin moisturization, and protection against oxidative damage.
