This study found that the pH levels of relaxers tested were corrosive to the skin and may contribute to alopecia in females with afro-textured hair.

This study found that the stability of the coiled-coil structure in human hair keratin is maintained by ion-pairing and hydrophobic interactions, which are disrupted as pH approaches 7.0.

This study introduced a new laser-only method called EKA for acne treatment, which is reported to be safe, painless, and heat-free, showing promising results for both acne and scar repair in initial sessions without combining with LED light.

This review outlines the current understanding of how pH contributes to root hair development and reports no new experimental findings.

In this study, researchers identified a novel p.R50X mutation in the vitamin D receptor gene, linked to hereditary vitamin D-resistant rickets in two siblings.

In this study, 95% of respondents reported severe hair breakage or loss after using the Rio Hair Naturalizer System, with many experiencing significant and lasting hair loss.

This study reports that six shampoo brands in Saudi Arabia generally comply with the national specifications, demonstrating good physicochemical properties such as foam stability and pH levels.

This article reviews the impact of H2O2-redox homeostasis on hair follicle pigmentation via tyrosinase and associated mechanisms, discussing primarily findings from murine models without providing new clinical results for humans.

This study found that hair absorbs significant amounts of NaBr from solution, with absorption increasing linearly with solution concentration and additional effects noted with acidic or basic solutions.

This study found that the uptake of molecules by hair is influenced by both hydrophobic and ionic charge interactions, with binding affinity decreasing as pH approaches the solute's dissociation constant.

This study investigated various proteins as eco-friendly hair perming agents for Asian hair and found that bovine serum albumin and keratin achieved perming results comparable to commercial products, while also increasing hair moisture, indicating a protective effect during heat styling.

This study found that polyquaternium-68 at pH 9 achieved the greatest hair deposition, while polyquaternium-44 demonstrated the best wash resistance at pH 6.

In this study, EPC-K, a compound with antioxidant and moisturizing effects, was found to decompose significantly under certain conditions, impacting its stability in quasi drug hair-growing products.

This review summarizes the link between acne pathogenesis and skin barrier dysfunction, noting that more severe acne correlates with greater skin barrier damage, but reports no new clinical results.

This review article describes the ingredients and evaluation tests for formulating a hair serum aimed at improving hair growth and preventing hair loss, highlighting the roles of Citrus sinensis, Nigella sativa, flax seed, and coconut oil in addressing hair and scalp health.

This study found that sensitive scalp is characterized by increased pH levels, redness, altered sebum composition, and a disrupted microbiome, suggesting these features could inform treatment approaches.

This study found that using Urtica cannabina extract shampoo led to increased levels of copper, zinc, and iodine in the scalp hair of Mongolian women, along with improvements in hair growth, diameter, and density compared to a regular shampoo.

This study found that formulation factors like pH, viscosity, and chemical enhancers can significantly influence intrafollicular hydrocortisone permeation in vitro, with higher pH and enhancers reducing follicular contribution.

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.

This review examines the pH levels of various shampoos and reports no new clinical results, highlighting the potential importance of labeling pH values on shampoo packaging for hair and scalp health.

In this study, varying pH levels from 3 to 12 were found to impact hair structure and proteins, with optimal hair health observed between pH 5 and pH 7, while extreme acidic or alkaline conditions notably affected hair morphology and proteome.

This study found that dexamethasone-loaded Eudragit® L 100 nanoparticles displayed controlled drug release depending on pH levels, with minimal toxicity to human fibroblasts.

In this study, scalp hydration and pH levels were not significantly different between hijab-wearing and non-hijab-wearing women, suggesting that hijab-wearing does not impair scalp health if there's no history of underlying scalp or skin disorders and the hijab is not worn damp.

This study found that bleached hair showed optimal protein structural integrity and tensile strength at pH 5, with significant changes in cross-linking, water content, and diameter at more alkaline or acidic levels.

This study suggests that elevated copper levels in domestic tapwater, exacerbated by its aggressive properties, likely contribute to green hair by damaging the cuticle and increasing copper uptake.

In this study, researchers observed that Malassezia species show different lipid metabolism and growth patterns depending on pH, with slightly acidic conditions promoting beneficial lipid bio-conversion for skin health, while neutral pH resulted in lower growth and lipid content, potentially negatively impacting the skin.

This study found that hair fibers broke down and lost keratin in extremely basic conditions, revealing the inner medulla and changing the color of the fibers.

This review highlights emerging evidence that biophysical and metabolic cues, such as oxygen levels and tissue mechanics, significantly influence skin stem cell behavior, which is crucial for developing advanced wound healing therapies beyond traditional infection and inflammation control.

This study describes the development and testing of an IoT-based smart pot system designed for optimal lavender plant care, utilizing temperature, pH, and soil type monitoring via a Node MCU to control watering based on soil moisture levels.
