Infrared and Raman imaging can non-destructively analyze hair structure and help diagnose hair conditions.

Hair treatments cause significant structural changes, especially with excessive heat, regardless of ethnicity.

Human hair shows promise for non-invasive medical testing, but more research is needed to standardize its use.

Removing external lipids from hair reduces moisture and increases strength, while removing internal lipids decreases water permeability.

Surfactants in shampoos and conditioners remove some but not all lipids from hair, and more research is needed to understand their full impact.

Adding human hair to cement can make it tougher and better insulated but also more porous.

The method shows that zinc pyrithione and climbazole from anti-dandruff shampoo effectively reach the scalp.

Different scalp imaging methods are important for studying hair and scalp health and require more volunteers for better evaluation.

Different tests are used to see how hair care products affect hair, and choosing the right test is important for accurate results.

ATG effectively reduces hair frizz without damaging hair strength.

Rice derivatives in conditioners protect and improve hair health.

Different oils affect hair flexibility and strength, with their impact varying on whether hair is virgin or bleached.

Porcine skin is very similar to human skin, making it a useful model for research.

Researchers created a new light source that improves chemical imaging by removing background noise.

Teratoma hair is similar to scalp hair but has a rougher surface and lower adhesive force.

Nano-sized lipid particles increase dexamethasone's skin penetration and create a reservoir in the skin layers.

Multiphoton microscopy is a promising tool for detailed skin imaging and could improve patient care if its challenges are addressed.

Raman spectroscopy is promising for measuring and enhancing drug delivery in alopecia treatments.

Zinc pyrithione dissolves quickly on the skin and in hair follicles, especially in smaller particles.

The document concludes that there is no agreed-upon best method for measuring drug delivery within hair follicles and more research is needed to validate current techniques.

New imaging techniques show testosterone delays hair growth and shrinks follicles in mice, but have limited depth for viewing.

Diamond nanoparticles can penetrate skin and reach hair follicles, useful for imaging applications.

K18® and Olaplex® both effectively repair bleached hair, improving its strength, smoothness, and overall health.

Hair follicles may soon be used more for targeted and systemic drug delivery.

The skin is a complex barrier for drug penetration, but understanding its structure and interactions can improve drug delivery methods.

Green-synthesized nanoparticles can effectively target cancer cells, reducing side effects and improving treatment.

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

Human hair varies widely and should be classified by curl type rather than race.

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.

A new method accurately measures amino acids in treated hair, showing bleaching reduces amino acids while protein treatments increase them.
