Liposomal systems show promise for delivering drugs through the skin but face challenges like high costs and stability issues.

Alopecia areata causes hair loss, has no cure, and various treatments exist.

Estrogen therapy can reduce skin aging but has cancer risks.

Stem cell self-renewal is complex and needs more research for full understanding.

Antiandrogens are somewhat effective in reducing excessive hair growth in women.

Laser hair removal effectiveness depends on targeting hair structures without harming the skin, and improvements require more research and expert collaboration.

Some drugs can cause hair loss or increase hair growth, but these effects are usually reversible when the drug is stopped.

Hormone therapy is essential for transgender individuals but requires careful management due to possible metabolic effects.

Cathepsin L is essential for normal hair growth and development.

The Sonic hedgehog pathway is crucial for new hair growth during mouse skin healing.

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

Too much androgen can cause hair loss; finasteride may help.

Understanding hair follicle anatomy helps diagnose hair disorders.

Eating less sugar, milk, and saturated fats and more vegetables and fish may help treat and prevent acne.

Minoxidil promotes hair growth in male pattern baldness.

Different types of stem cells with unique roles exist in blood, skin, and intestines, and this variety is important for tissue repair.

The document recommends using both clinical evaluation and various measurement methods to assess skin greasiness, considering factors like temperature and hormones.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Stem cells in the hair follicle are regulated by their surrounding environment, which is important for hair growth.

Different types of stem cells and their environments are key to skin repair and maintenance.

Electrolysis is effective for permanent hair removal, but technique is key to avoid scarring, and sometimes hormonal treatment is needed for women with hirsutism.

The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.

Modulating BMP activity changes the number, size, shape, and type of ectodermal organs.

Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.

Mouse hair follicle cells briefly grow during the early hair growth phase, showing that these cells are important for starting the hair cycle.

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.

Prolactin contributes to hair loss by promoting hair follicle shrinkage and cell death.

Probiotic bacteria improved skin and hair health in aged mice.

Oxidative stress contributes to hair graying and loss as we age.

The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.
