Hair can regrow in large wounds through a process similar to how hair forms in embryos, and understanding this could lead to new treatments for hair loss or scarring.

UV exposure causes hair thinning, graying, and changes in hair growth cycles in mice.

Disrupted stem cell signals in hairpoor mice cause hair loss.

β-Catenin is essential for new hair growth after skin injury.

A specific enzyme is essential for proper hair follicle stem cell development and healthy skin.

The research found genes and miRNAs that may control hair growth in Forest Musk Deer.

MicroRNAs are crucial for skin development, regeneration, and disease treatment.

Microneedling is an effective and minimally invasive treatment for hair loss.

HA-stimulated stem cell vesicles improved hair growth in male mice with androgenetic alopecia.

Justicia procumbens extract may help prevent hair loss and improve hair thickness and shine in a type of hair loss condition.

Tianma Gouteng decoction may help prevent hair loss and promote hair growth.

Costunolide helps human hair cells grow and can stimulate hair growth in mice.

XIST RNA helps regenerate hair follicles by targeting miR-424 and activating hedgehog signaling.

The conclusion is that the cornea has two types of stem cells, with Lrig1+ cells being key for renewal in aging corneas, independent of CD44.

Blocking Wnt/β-catenin signaling with EGF receptor is necessary for proper hair growth.

Ezh2 controls skin development by balancing signals for dermal and epidermal growth.

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

Androgen receptor activity blocks Wnt/β-catenin signaling, affecting hair growth and skin cell balance.

PI3K/Akt pathway is crucial for hair growth and regeneration.

Annurca apple extract promotes hair growth by changing hair follicle metabolism to boost keratin production.

Pantothenic acid helps mink hair follicles grow by affecting certain cell signals.

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.

Targeting the HEDGEHOG-GLI1 pathway could help treat keloids.
