Hair follicles help absorb and store topical compounds, aiding targeted drug delivery.

The hedgehog signaling pathway is crucial for hair growth but not for the initial creation of hair follicles.

Latanoprost can make eyelashes longer, thicker, and darker.

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.

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

Liposomes improve drug delivery and reduce skin irritation in dermatology.

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

Antibiotics can reduce acne but may lead to resistant bacteria, and understanding the skin's bacteria is important for treatment.

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.

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

Adult female acne treatment should be personalized, considering individual preferences and pregnancy, using various topical and oral medications while managing side effects and resistance.

Hair grows faster in the morning and is more vulnerable to damage from radiation due to the internal clock in hair follicle cells.

The document concludes that understanding the sebaceous gland's development and function is key to addressing related skin diseases and aging effects.

Skin surface lipids are important for skin health and altering them could help prevent aging and treat skin conditions.

The human hair follicle can store topical compounds and be targeted for drug delivery with minimal side effects.

Eating a high-glycemic diet may worsen acne by increasing certain protein levels and expressions in the skin.

The document concludes that understanding the genes and pathways involved in hair growth is crucial for developing treatments for hair diseases.

The circadian clock influences the behavior and regeneration of stem cells in the body.

SAHA syndrome is a condition in women involving skin and hair issues, often related to hormonal imbalances, and is treated based on the underlying cause.

FFA's causes may include environmental triggers and genetic factors.

Nonionic liposomes are the best for delivering genes to skin cells.

The document concludes that for hair and feather growth, it's better to target the environment around stem cells than the cells themselves.

Human hair follicle cells can grow hair when put into mouse skin if they stay in contact with mouse cells.

Sebaceous glands in the skin play a key role in absorbing the antiandrogen drug RU 58841, especially when it's encapsulated in liposomes.

Light can turn on hair growth cells through a nerve path starting in the eyes.

Both mouse and rat models are effective for testing alopecia areata treatments.
