Modifying certain signals in the body can help wounds heal without scars and regrow hair.

Certain hairstyles can cause scalp diseases, smoking is linked to hair loss, 5% minoxidil foam is effective for hair loss treatment, and various factors influence wound healing and hair growth.

Bone-marrow and epidermal stem cells help heal wounds differently, with bone-marrow cells aiding in blood vessel formation and epidermal cells in hair growth.

Japanese researchers created new hair follicles from human cells that grew hair when put into mice, and other findings showed a link between eye disease severity and corneal thickness, gene mutations affecting hearing and touch, and the safety of the shingles vaccine for adults over 50.

IL-36α helps grow new hair follicles and speeds up wound healing.

Researchers created human hair follicles using a new method that could help treat hair loss.

Hydrogels could lead to better treatments for wound healing without scars.

The document concludes that better targeted treatments are needed for wound healing, and single-cell technologies may improve cell-based therapies.

Hydrogel scaffolds can help wounds heal better and grow hair.

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.

Nonpalmoplantar skin cells can be made to express keratin 9 by interacting with palmoplantar fibroblasts.

Tiny vesicles from stem cells could be a new treatment for healing wounds.

New injectable hydrogels with gelatin, metal, and tea polyphenols help heal diabetic wounds faster by controlling infection, improving blood vessel growth, and managing oxidative stress.

Injecting lab-grown hair cells into the scalp can regrow hair.

Softer hydrogels help wounds heal better with less scarring.

Using stem cells from fat tissue can significantly improve wound healing in dogs.

The gel with icariin speeds up wound healing, reduces scarring, and helps hair growth by controlling BMP4 signaling. It also reduces inflammation and improves wound quality in mice, adapts to different wound shapes, and gradually releases icariin to aid healing. It also prevents too much collagen and myofibroblast formation during skin healing.

Transplanting hair follicles into chronic ulcers helps them heal better.

The skin's microbiome helps hair regrow by boosting certain cell signals and metabolism.

The document concludes that treatments for cicatricial alopecia are not well-supported by evidence, but hair transplantation shows more predictable and satisfactory results.

Exosomes could potentially enhance tissue repair and regeneration with lower rejection risk and easier production than live cell therapies.

The biofilm-dispersing wound gel helps wounds heal faster and prevents infection.

Activating TRPA1 reduces scarring and promotes tissue regeneration.

Exosomes show promise for improving wound healing, reducing aging signs, preventing hair loss, and lightening skin but require more research and better production methods.

Intense pulsed light treatment mainly damages pigmented hair parts but spares stem cells, allowing hair to regrow.

Disrupting Notch signaling in blood vessels increases scarring during wound healing in mice.

Lab-made tissues from dog fat stem cells can help grow hair by releasing a growth factor.

Tissue from dog stem cells helped grow hair in mice.

Testosterone may worsen hair loss by affecting hair growth signals, while different prostaglandins can either hinder or promote hair growth.

Leaving non-absorbable sutures in for 6 months reduces scar stretching and width.
