Low-level laser therapy is a safe, painless method that effectively treats acne and improves skin without post-treatment care.
research Root hair growth from the pH point of view
pH changes are crucial for root hair growth because they affect enzymes and proteins that control the cell wall and growth.
research Two siblings with a novel nonsense mutation, p.R50X, in the vitamin D receptor gene
A new gene mutation causes vitamin D-resistant rickets and hair loss in two siblings.
research A Nationwide Outbreak of Alopecia Associated With the Use of a Hair-Relaxing Formulation
A hair-straightening product caused widespread hair loss and scalp injuries, mainly affecting African American women.
research Pharmaceutical evaluation of different shampoo brands in local Saudi market
All evaluated shampoos meet Saudi standards.
research The redox - biochemistry of human hair pigmentation
Human hair color is influenced by complex biochemical processes involving enzymes and reactive oxygen species.
research Kinetics and Equilibrium of Solute Diffusion into Human Hair
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.
research Proteins as Hair Styling Agents
Proteins like BSA and keratin can effectively style hair and protect it, offering eco-friendly alternatives to chemical products.
research Examining polyquaternium polymers deposition on human excised hair fibers
Certain polymers can stick to hair and increase volume, working best at a pH of 7 to 9.
research Stability Studies on L-Ascorbic Acid dl-α-Tocopherol Phosphoric Acid Diester Potassium Salt (EPC-K)
EPC-K is stable except at very acidic pH or when exposed to sunlight, and it can decompose in low ethanol concentrations.
research Research Progress of Skin Barrier and Acne
Impaired skin barrier function worsens acne.
research 1302 Disturbed sebum and microbiome composition in sensitive scalp
Sensitive scalp has higher pH, more redness, abnormal sebum, and altered bacterial makeup.
research The change of copper, zinc, iodine, and selenium contents in the scalp hair of healthy females and the efficacy of herbal extract shampoo treatment
Herbal extract shampoo increased certain minerals in hair and improved hair growth and scalp health.
research Factors influencing hydrocortisone permeation into human hair follicles: Use of the skin sandwich system
Different factors like pH, gel type, and chemical enhancers affect how well hydrocortisone gets into hair follicles, and less hydrated skin doesn't work well with the test method.
research Festschrift in honor of the 65th birthday of Dr. Howard I. Maibach
Antiyeast treatments work better for seborrheic dermatitis than steroids, and other findings include increased skin bacteria under plastic wrap, a nasal cell defect in Staphylococcus aureus carriers, quick resolution of certain skin reactions, high rubber latex allergy in spina bifida patients, and glyceryl monopentadecanoate's effectiveness for male hair loss.
research Synthesis and Validation of Functional Nanogels as pH-Sensors in the Hair Follicle
Scientists created tiny pH-sensing gels that can safely measure the pH levels inside hair follicles.
research PEG-Immobilized Keratin for Protein Drug Sequestration and pH-Mediated Delivery
PEG and keratin scaffolds can effectively deliver protein drugs by controlling release based on pH levels.
research Sodium chloride reduces growth and cytosolic calcium, but does not affect cytosolic pH, in root hairs of Arabidopsis thaliana L.
Sodium chloride slows root hair growth by altering calcium levels, not pH.
research Rat steroid 5α-reductase kinetic characteristics: Extreme pH-dependency of the type II isozyme in prostate and epididymis homogenates
The activity of a specific rat enzyme in the prostate and epididymis is highly dependent on the acidity level.
research Formulation and in vitro evaluation of polymeric enteric nanoparticles as dermal carriers with pH-dependent targeting potential
Scientists created tiny particles that release medicine on the skin and in hair, working better at certain pH levels and being safe for skin cells.
research Copper in Green Hair: A Quantitative Investigation by Electron Probe X-Ray Microanalysis
Green hair has high copper levels due to contaminated water and damaged hair cuticles.
research The shampoo pH can affect the hair: Myth or Reality?
Shampoo pH can affect hair health, with alkaline shampoos potentially causing damage and acidic shampoos reducing frizz.
research Characteristics of Malassezia furfur at various pH and effects of Malassezia lipids on skin cells
Malassezia furfur lipids improve skin health at pH 6.
research The Degradative Characteristics of Hair in The Water Samples with Altered pH
Hair fibers degrade and change color in very basic water.
