Using longer PEG chains helps nanoparticles penetrate hair follicles better, improving drug delivery for conditions like alopecia.

Killing specific cells in hair follicles can lead to hair growth problems in mice.

Hair stiffness is higher when it has more para-like cortical cells.

Kir6.1 mutations in Cantú syndrome increase channel sensitivity and hyperpolarization, while SUR2B mutations do not.

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

Minoxidil and finasteride treat hair loss; more research needed for other options.

Surface-modified nanoparticles mainly use non-follicular pathways to enhance skin permeation of ibuprofen and could improve treatment for inflammatory skin diseases.

Massage increases how deep both rigid and flexible liposomes can go into skin, with flexible ones going deeper, and covering the skin (occlusion) helps rigid ones more.

Transfollicular drug delivery is promising but needs more research to improve and understand it better.

Dutasteride-loaded nanoparticles coated with Lauric Acid-Chitosan show promise for treating hair loss due to their controlled release, low toxicity, and potential to stimulate hair growth.

Hair absorbs molecules differently based on their size, charge, and love for water, and less at higher pH; this can help make better hair products.

Targeting colon cancer stem cells might lead to better treatment results.

Increasing mir-302 turns human hair cells into stem cells by changing gene regulation and demethylation.

Zinc oxide nanoparticles in sunscreen do not penetrate deep into the skin.

Niosomes are a promising, stable, and cost-effective drug delivery system with potential for improved targeting and safety.

Biomaterials with MSC-derived substances could improve tissue repair and have advantages over direct cell therapy.

Tiny pollution particles called PM2.5 can harm skin cells by causing stress, damage to cell parts, and cell death.

Dutasteride and finasteride may reduce sperm count and volume but don't affect movement or shape; effects are reversible after stopping.

The ZIP7 gene helps control zinc levels in cells by moving zinc from the Golgi apparatus to the cytoplasm.

A new microneedle patch made from hair proteins helps regrow hair faster and better than current treatments.

Keratose, derived from human hair, is a non-toxic biomaterial good for tissue regeneration and integrates well with body tissues.

Particles around 100 nm can penetrate and stay in hair follicles without passing through healthy skin, making them safe for use in topical products and useful for targeted drug delivery.

The hydrogel with a 1:3 ratio of hydroxyethyl cellulose to hyaluronic acid is effective for delivering drugs through the skin to treat acne.

Tiny particles from stem cells help activate hair growth cells and encourage hair growth in mice without being toxic.

Liposomes could improve how skin care products work but are costly and not very stable.

Targeting hair follicles can improve skin treatments and reduce side effects.

New single-cell analysis techniques are improving our understanding of stem cells and could help in treating diseases.
