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.

Human hair follicle stem cells help repair tendon injuries.

Low-level Laser Therapy may help reduce inflammation, pain, and aid healing, but more research is needed to confirm its effectiveness and establish standard treatment guidelines.

Stem cell niches are crucial for regulating stem cell behavior and tissue health, and their decline can impact aging and cancer.

Male and female skin differ due to hormones, affecting conditions like hair loss, acne, and skin cancer, and suggesting a need for gender-specific treatments.

Nanoparticles improve drug delivery through the skin but more research is needed on their long-term effects and skin penetration challenges.

Estrogen therapy can reduce skin aging but has cancer risks.

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

Epidermal stem cells help heal severe skin wounds and have potential for medical treatments.

The skin's internal clock affects healing, cancer risk, aging, immunity, and hair growth, and disruptions can harm skin health.

Smoking harms the skin, causing early aging and increasing cancer risk, but stopping smoking can improve skin health.

Liposomes could improve how skin care products work but are costly and not very stable.

Skin fat helps with body temperature control and has other active roles in health.

The circadian clock is crucial for tissue renewal and regeneration, affecting stem cell functions and having implications for health and disease.

Mesenchymal stem cells show potential for skin healing and anti-aging, but more research is needed for safe use, especially regarding stem cells from induced pluripotent sources.

After menopause, women lose a lot of skin collagen, but estrogen replacement might improve skin health.

Fat-derived stem cells, platelet-rich plasma, and biomaterials show promise for healing chronic skin wounds and improving soft tissue with few side effects.

Platelet-rich plasma, taken from a person's own blood, can help rejuvenate skin, stimulate hair growth, and treat hair loss, but more research is needed to confirm its safety and effectiveness.

Platelet-Rich Plasma (PRP) shows promise for treating various skin conditions, but more research is needed to standardize its use.

Skin organoids are a promising new model for studying human skin development and testing treatments.

MALDI Imaging Mass Spectrometry is a useful method for studying skin conditions, but sample preparation is crucial for accurate results.

New skin substitutes for treating severe burns and chronic wounds are being developed, but a permanent solution for deep wounds is not yet available commercially.

GMG-43AC may help reduce unwanted hair growth and treat certain hair loss conditions.

Skin aging is caused by stem cell damage and can potentially be delayed with treatments like antioxidants and stem cell therapy.

Hair follicle bulge cells don't help skin regrow after glucocorticoid damage; interfollicular epidermis cells do.

Fibroblasts are important in healing diabetic wounds, but high sugar levels can harm their function and slow down the healing process.

Local skin glucocorticoid production is crucial for healthy skin, and its disruption can lead to skin diseases.

Injury changes how hair follicle stem cells behave, depending on the hair growth stage.

Cell therapy shows promise for treating severe psoriasis but needs more research to confirm safety and effectiveness.

Vitamin D made by the skin plays a role in immune defense and skin health, and more research is needed to understand its full effects.
