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

The article concludes that while we understand a lot about how melanocytes age and how this can prevent cancer, there are still unanswered questions about certain pathways and genes involved.

Blocking BACE1 and BACE2 enzymes causes hair color loss in mice.

Skin grafts are effective for chronic leg ulcers, especially autologous split-thickness grafts for venous ulcers, but more data is needed for diabetic ulcers.

The research found that anovulatory young women have higher androgen and hormone levels than those who ovulate, suggesting immature hormonal regulation rather than a specific condition.

Scientists have created a new hair loss treatment using ultrasound to deliver gene-editing particles, which resulted in up to 90% hair regrowth in mice.

Caffeine nanocrystals for skin products stay stable with the right stabilizer, but grow in size at higher temperatures.

Beard and scalp hair cells have different gene expressions, which may affect beard growth characteristics.

Eucalyptol and oleic acid in nanoemulsions improve minoxidil delivery to hair follicles, potentially enhancing hair loss treatment.

The protein SLC1A3 is important for activating skin stem cells and is necessary for normal hair and skin growth in mice.

The study concluded that scalp tumors show different patterns based on age, gender, and tumor thickness, and emphasized the importance of early detection and scalp examinations.

The new CoQ10 gel protects mouse skin better against aging from UV light than the old gel.

New lipid nanoparticles show promise for delivering hair loss treatments but need improvement for better skin penetration.

PDI helps restore over-bleached hair's strength and structure by attaching special peptides.

Autophagy is crucial for normal sebaceous gland function and sebum composition.

Daughters of women with PCOS generally experience normal puberty but may have more body hair and different body fat distribution.

Using certain small proteins with a growth factor and specific materials can increase the creation of neurons from stem cells.

Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.

Finasteride cream helps hair growth with less side effects.

Minoxidil prevents serotonin loss from MDMA by affecting potassium channels and increasing Akt phosphorylation.

Removing external lipids from hair reduces moisture and increases strength, while removing internal lipids decreases water permeability.

MRI can effectively image skin structures noninvasively.

Cat color patterns are determined early in development by gene expression and epidermal changes, with the Dickkopf 4 gene playing a crucial role.

Teucrium polium extracts are non-toxic and effectively speed up wound healing.

New gel formulas without ethanol and propylene glycol, containing a minoxidil-methyl-β-cyclodextrin complex, have been created for treating hair loss.

Follicular unit hair transplantation is the standard method for natural-looking hair restoration in androgenic alopecia.

Two non-steroidal antiandrogens, RU 58841 and RU 56187, form a common metabolite at different rates, which may influence their effects; RU 56187 could be used for prostate cancer treatment and RU 58841 for acne treatment.

Caffeine penetrates skin quickly through open hair follicles, but less through closed ones, with levels becoming equal after 22 hours.

Lepidium sativum seed extracts helped reduce inflammation and improve insulin response in obese rats on a high-fat diet.
