Human hair keratins K85 and K35 create unique filament patterns important for early hair formation.

A protein called desmoglein 3 is important for keeping hair follicle stem cells inactive and helps in their regeneration.

Nanocrystals and nanoparticles can enhance drug delivery for skin applications by improving solubility and dissolution rates.

Keratin filaments' elasticity is influenced by their terminal domains and surrounding medium.

Micelles can change cetirizine's ionization, affecting its effectiveness in treatments.

The Gas-Antisolvent process can be effectively modeled and optimized to create Finasteride, a hair growth drug.

Minoxidil dissolves better in propylene glycol + water than in supercritical CO2.

The study created a new type of microsphere that effectively regrows hair.

Minoxidil's effectiveness decreases as vehicle evaporates; concentration and thermodynamic activity matter.

Hair loss is caused by mechanical, thermal, and metabolic factors, not just hormones.

Hair loss is caused by mechanical, thermal, and metabolic stress, not just hormones.

Menthol-based microemulsions improve skin delivery of finasteride and silodosin.

Using supercritical carbon dioxide can change the size of Hinokitiol particles.

EPC-K is stable except at very acidic pH or when exposed to sunlight, and it can decompose in low ethanol concentrations.

Human hair becomes weaker and stretches more easily at higher temperatures.

The gel and tonic were not stable.

Chemical modifications can alter hair's stability and flexibility, with hydrophobic interactions helping maintain structure in humid conditions.

Thermal protectants help reduce hair damage from heat styling.

Thermal protectants help reduce hair damage from heat styling.

The hair tonics with galangal and Aloe vera extracts were stable and met standards.

A new cooling device keeps a constant temperature for medical procedures, improving results.

Hair analysis for drugs needs a better understanding of how drugs enter hair, considering factors like hair structure and pigmentation.

Nanoparticles improve minoxidil skin permeation, but more research needed for effective hair growth.

More ethanol increases minoxidil delivery, but too much lowers efficiency.

Finasteride poorly inhibits type 1 5AR, affecting its effectiveness.

Wool and hair fibers absorb moisture similarly due to their keratin structure, with the amount of non-crystalline areas affecting the moisture uptake.

Hair increases in size when it absorbs water, and treatments like bleaching affect how much water it can take in.

Rubbing skin increases absorption of water-soluble drugs from lotions and creams, but not oil-soluble drugs.
