Vesicle-based therapies from stem cells and plants improve burn healing and could be safe, scalable alternatives to cell transplants.

Garlic can help hair grow by activating certain growth pathways, and it works whether you eat it or apply it to your scalp.

Caffeine, niacinamide, and panthenol may improve hair growth, fullness, and healing when applied to the scalp.

Hair's molecular structure is mostly consistent, but genetic differences affect lipid types, which could help diagnose diseases.

Understanding hair anatomy and growth is key to treating hair loss.

Hormones, especially androgens, affect hair growth and can cause hair loss or excess hair in both men and women.

Researchers identified key cell types and genes involved in hair and skin diseases.

Hair cortisol measurement is a promising, non-invasive tool for monitoring cortisol exposure over time.

Hair shedding that lasts more than 6 months may need medical tests, but often just reassurance is enough.

Blocking a protein called prostaglandin D2 might help treat hair loss.

Interleukin-15 can help hair growth and protect hair follicles.

Different causes of hair loss require specific treatments, and most men and women will experience some form of hair thinning as they age.

Hair cuticles remain stable and resilient under stress due to strong protein content and crosslinking.

Testosterone helps beard and axillary hair cells grow by releasing growth factors from dermal papilla cells.

Hair can show increased cortisol levels during late pregnancy.

Testosterone increases hair follicle cell growth when beard or axillary skin cells are present together.

Hair cells grown in a lab showed specific hair proteins.

All-trans retinoic acid causes hair loss by increasing TGF-β2 in hair follicle cells.

Adiponectin may stimulate hair growth and could be a potential treatment for promoting hair growth.

Hair organoids are effective for testing hair loss treatments.

Minoxidil rejuvenates hair follicles and reduces aging signs in male pattern baldness.

TGFβ-2 may cause hair loss in androgenetic alopecia.

MSC-derived exosomes may help in skin repair and regeneration.

EZH2 levels decrease as fetuses develop and are higher in adult skin, which may affect skin growth and repair.

Chemotherapy can cause hair changes similar to alopecia areata, which might lead to misdiagnosis.

Chemotherapy causes permanent hair follicle damage by triggering stem cell loss.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Baldness is often hereditary and linked to male hormones, becoming noticeable when half the hair is lost.

TRH in hair follicles can influence hair color by increasing melanin.

Nanotechnology can improve cervical cancer treatment by targeting drugs better and reducing side effects.
