Different factors like pH, gel type, and chemical enhancers affect how well hydrocortisone gets into hair follicles, and less hydrated skin doesn't work well with the test method.

Applying heat with certain chemicals can greatly improve how well isotretinoin gets into the skin through hair follicles.

Different body parts have varying levels of certain hair follicle markers.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

Lgr5 is a marker for active, self-renewing stem cells in the intestine and skin, important for tissue maintenance.

Certain proteins and their receptors are more active during the growth phase of human hair and could be targeted to treat hair disorders.

The proteins transthyretin and megalin are more present in the growth phase of hair, suggesting they might affect hair health and growth.

Melanocyte precursors in human fetal skin follow a specific migration pattern and some remain in the skin's deeper layers.

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

Aging causes skin stem cells to work less effectively.

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.

BLIMP1 is essential for skin maintenance but not for defining sebaceous gland progenitors.

Melatonin protects skin against UV damage by regulating various cellular processes.

Wnt proteins from certain skin cells are crucial for normal hair growth and renewal.

Hair and skin can regenerate without bulge stem cells due to other compensating cells.

Skin cells show flexibility in healing wounds and forming tumors, with potential for treating hair disorders and chronic ulcers.

UV exposure reduces Lgr6+ stem cells in mouse skin and they don't significantly contribute to skin cancer development.

Researchers used a laser to create advanced skin models with hair-like structures.

The skin basement membrane is specialized for different tissue interactions, important for hair growth and attachment.

Activin increases skin tumor formation, skin Tregs help hair growth, lymph-node removal doesn't improve melanoma survival, cells can revert to stem cells in wound healing, and skin bacteria produce peptides that may treat infections.

Scientists found gene mutations that affect hair loss, skin stem cells, and skin disorders, and identified drugs that may help treat blood vessel and skin conditions.

Activating cAMP and ATP improves hair growth and strength.

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

Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

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

Hair follicles help attract immune cells to the skin during stress.

The study found that sweat glands contain different types of stem cells that help with healing and maintaining healthy skin.

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

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.

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