In this study, tresses treated with pH 1.0 acid straightener showed better straightening but more damage to hair properties compared to those treated with pH 2.0.

This study found that the acidic hair straightening formulation at pH 1.0 improved hair alignments and straightening effectiveness more than pH 2.0, but it weakened fiber strength and affected hair color and composition.

This study identified the presence of recognizable organelles, such as lysosomes and mitochondria, in both the keratinized fiber and the hardened inner root sheath of the Romney wool follicle.

This study found that acid and alkaline phosphatases serve different functions in Beagle dog skin, with ALP primarily involved in growth processes and ACP in phospholipid breakdown.

This study observed greater clinical improvement in patients with alopecia areata who received individualized homoeopathic constitutional treatment compared to those who received Acid Phos, but further research with objective measures is needed to confirm these findings.

This article reviews the use of platelet rich plasma in treating androgenetic alopecia and discusses the potential limitation of pain from injections, without presenting new clinical results.

This study found that glyoxylic acid caused more protein loss in hair compared to traditional alkaline straighteners, though both types of treatments showed comparable effects on hair tensile strength.

This study found that chondroitin sulfate levels were higher than hyaluronic acid in skin and hair follicle samples, with the highest concentration observed in prekeratin of hair follicles and wool fibers.

This study found that p2y5 functions as a novel LPA receptor involved in the G13-Rho signaling pathway, with implications for human hair growth, and proposes renaming it to LPA6.

This study found that sebum free fatty acids may enhance the antibacterial defense of human sebaceous glands by upregulating the expression of the antimicrobial peptide hBD-2, potentially aiding in acne treatment.

This study identified an unexpected critical role for the FATP4 protein in skin and hair development in mice, linking it to a potential candidate gene for restrictive dermopathy in humans.

This study reported the first known occurrence of citrulline in an animal protein, specifically in the fibrous protein of hair follicle inner root sheaths.

Alpha-hydroxy acids, like glycolic acid, safely improve skin issues and work on all skin types.

This study found that keratins have evolutionarily conserved and domain-selectively enriched amino acids, which likely reflect their unique structural roles, with distinct patterns observed among epidermal, hair, and simple-type epithelial keratins.

This review discusses the synthesis and biological activities of jasmonates, highlighting their potential as drugs and prodrugs, but reports no new clinical results; further research and trials are anticipated.

In this study, application of salicylic acid solution on mouse skin showed histologic changes without causing wounds or inflammation, observed immediately and up to 48 hours after treatment.

In this study, valproic acid treatment was associated with reduced biotinidase activity and improved skin lesions after biotin supplementation in children with seizures.

This study found that short-chain fatty acids produced by the skin microbe Propionibacterium acnes may drive inflammatory gene expression in sebocytes, potentially contributing to acne.

This review discusses various amino acid-derived plant defensive compounds and highlights their potential as drug leads due to their potent antimicrobial properties, but reports no new experimental results.

Made 8 minoxidil samples; 1 cocrystal, 7 salts formed.

The researchers found that inhibiting soluble epoxide hydrolase, either genetically or pharmacologically, delayed the onset of chemically induced seizures related to GABA antagonism in experimental models.

This study identified that the enzyme CYP2B12 is skin-specific and likely plays a role in the metabolism of arachidonic acid, a key component in lipid signaling within sebaceous glands.

This study suggests that activating retinoic acid signalling can inhibit Wnt signalling and induce regression in certain skin tumors, providing potential therapeutic strategies for tumor regression.

This study found that self-noncoding dsRNA activates TLR3 to stimulate intrinsic retinoic acid synthesis, promoting new hair follicle formation in wounded mice and showing similar gene expression changes in humans treated with rejuvenation lasers.

This review discusses the effects of valproic acid on immune cell activation and gene expression, potentially influencing infection outcomes and suggesting its promise for autoimmune and hypersensitivity condition management.

This study found that dutasteride-loaded nanostructured lipid carriers coated with a stearic acid-chitosan oligomer are stable, less cytotoxic, and suitable for topical delivery to promote hair growth.

This study found that hydroquinone caused structural damage to the skin of rats, while aloe vera reduced this damage, suggesting potential concerns for its use in skin lightening creams.

This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

This study reports that the autotaxin–LPA–LPA3 signaling pathway at the embryo-epithelial boundary plays a critical role in decidualization by up-regulating HB-EGF and COX-2 in the uterine epithelium.

This study found that while extracellular matrix components like hyaluronic acid promoted larger organoid formation, other matrix components hindered hair follicle germ assembly in an in vitro model.
