This study found that polysaccharide extracts from ginseng, green tea, shiitake, and aloe vera effectively protected human follicle dermal papilla and keratinocyte cells by promoting cell proliferation or inhibiting apoptosis, suggesting potential for these extracts as ingredients in cosmetics or pharmaceuticals to prevent hair loss.

This study found that an extract from the herbal medicine Ophioglossum vulgatum Linn. showed potential hair growth promotion and increased ATP and catalase activity in cell assays, suggesting its use in treating alopecia.

In this study, spirulina extract was reported to exhibit antioxidant properties and enhance cell proliferation in dermal papilla cells, suggesting its potential for scalp protection and possibly reversing hair loss.

This study found that stimulating the olfactory receptor OR2A4/7 with cyclohexyl salicylate promoted human hair growth and increased progeny of hair follicle epithelial stem cells in an ex vivo setting.

This study observes that TYK2 inhibition with BMS-986202 may extend hair follicle growth phases and decrease inflammatory cell markers in alopecia areata, suggesting potential for clinical application.

In this study, a serum containing Silybum marianum extract, Manganese PCA, and Lespedeza capitata extract improved hair growth and prolonged the anagen phase in a human scalp skin model.

This study found that in mice, chronic stress elevates corticosterone levels, which suppresses hair growth by keeping hair follicles in a prolonged resting phase.

This study found that actomyosin contractility in suprabasal keratinocytes influences the proliferation and differentiation of epidermal stem/progenitor cells by acting as a niche element in the skin.

The study concluded that a new method can effectively assess scalp sun damage in balding men, which increases with age and sun exposure.

This review discusses the use of phototherapy for treating different types of alopecia and reports its potential effectiveness without serious adverse reactions, but it emphasizes the need for further studies to optimize treatment parameters.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

This study found that LDE225, a novel Smo antagonist, shows potential as a topical treatment for basal cell carcinoma due to its high affinity binding and effective inhibition of tumor growth in preclinical models.

This review discusses the mechanisms of cell death in skin-associated processes and highlights potential therapeutic opportunities for targeting cell death to treat inflammatory skin diseases, but reports no new clinical results.

This study found that estradiol affects hair growth in mice by regulating the transition of hair follicles from rest to growth phases via the estrogen receptor pathway in the dermal papilla.

This review discusses the cell biological characteristics of the outer root sheath of normal human hair follicles and highlights some similarities and differences with trichilemmal tumors, but reports no new results.

This study found that epidermal-specific deletion of aPKCλ in mice disrupted hair follicle stem cell quiescence and regeneration, leading to abnormal hair cycling and skin changes.

This study reported that UVR induced PKCε phosphorylation of Stat3 in transgenic mice, suggesting a role in enhancing sensitivity to UVR-related skin cancer development.

This study found that mTOR signaling plays a crucial role in activating hair follicle stem cells by balancing BMP-mediated repression, essential for hair regeneration.
