Dandruff might be caused by changes in how hair follicles naturally release oils and an immune response to this imbalance.

Activating δ-opioid receptors can help hair grow.

Exosomes could be key in treating skin conditions and healing wounds.

Notch signalling helps skin cells differentiate and prevents tumors.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

The right cells and signals can potentially lead to scarless wound healing, with a mix of natural and external wound healing controllers possibly being the best way to achieve this.

Wnt3a protein, when packed in liposomal vesicles, can stimulate hair growth and could potentially treat conditions like hair loss.

Blood tests can help understand the genetic differences in people with alopecia areata, including how severe it is and if it's inherited.

A two-step method was created in 2015 to make more cells that help with hair growth, but they need to be combined with other cells for 4 days to actually form new hair.

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

Human nails and hair follicles have similar gene activity, especially in the cells that contribute to their growth and development.

New research shows that skin diversity is influenced by different types of dermal fibroblasts and their development, especially involving the Wnt/β-catenin pathway.

Exosomes from fat-derived stem cells can potentially improve hair growth and could be a new treatment for immune-related hair loss.

Exosomes show promise for improving wound healing, reducing aging signs, preventing hair loss, and lightening skin but require more research and better production methods.

Aging causes hair loss and graying due to stem cell decline and changes in cell behavior and communication.

Hair follicle stem cells can help treat ulcerative colitis in mice by releasing beneficial exosomes.

Mesenchymal stem cells show promise for effective skin repair and regeneration.

New tissue engineering strategies show promise for regenerating human hair follicles, which could improve hair loss treatments.

NMN could potentially treat hair loss by reducing oxidative stress and improving cell health.

Nicotinic acid reduces excessive oil production in skin cells by activating a specific receptor, which could help treat acne.

Hair loss in male pattern baldness is linked to changes in specific genes and proteins that affect hair growth and scalp health.

The study identified unique genes in hair follicle cells and their environment, suggesting these genes help organize cells for hair growth.

Dermal fibroblasts have adjustable roles in wound healing, with specific cells promoting regeneration or scar formation.

Aging slows wound healing due to weaker cells and immune response.

Genetic defects in the glucocorticoid receptor gene can cause conditions with abnormal sensitivity to stress hormones, and other factors may also affect this sensitivity.

Stem cells and their secretions could potentially treat stress-induced hair loss, but more human trials are needed.

The article concludes that creating a detailed map of normal human skin at the single-cell level is important.

Wounding may stimulate hair growth, but more research is needed to confirm the safety and effectiveness of related treatments.

Overexpression of sPLA2-IIA in mouse skin reduces hair stem cells and increases cell differentiation through JNK/c-Jun pathway activation.

Using extracellular vesicles from stem cells can help hair grow by affecting scalp cells and hair follicles.
