In this study, the synthesis of C-4 and C-6 bridged haptens of 11 alpha-hydroxyprogesterone revealed an unexpected formation of a C-4 substituted product using a 6-bromo derivative, contrary to prior reports.

This study found that selected polymeric pretreatments on hair can significantly reduce breakage and protect against thermal damage from hot flat irons by maintaining cuticle integrity and moisture.

In this study, clinically used preoperative skin preparations with povidone iodine and chlorhexidine gluconate did not meet FDA log-reduction standards for bacterial bioburden in a porcine model, suggesting persistent infection risks.

In this study, using tyrosine as a cross-linking agent for hair perming showed better initial results compared to commercial products, though efficiency decreased after washing without compromising hair strength.

In this study, solar drying of Punicagranatum was found to be the most effective, achieving a 65.26% drying rate compared to shade and convective drying methods.

The researchers reported that increasing protein content in human hair keratin/calcium alginate blend films led to larger molecular aggregates, which influenced the films' physical properties such as light transmittance and tensile strength.

This study found that enzyme depilation of lambskins can cause damage due to the removal of collagen VI, suggesting the need for a protease that avoids this interaction for successful application.

This study verified that a new straightening process involving a flat iron, ammonium thioglycolate, and hydrogen peroxide may permanently straighten wavy hair by eliminating disulfide bond distortions.

This study found that using natural polyphenol cross-linkers like tannic acid and green tea extract during perm treatments improved perming efficiency, wave maintenance, and hair protection compared to a control group.

This study found that a finasteride topical gel formulation using propylene glycol and Tween® 80 showed significantly enhanced permeation compared to a control formulation without these enhancers.

This study found that applying a hair mist with dandelion extract before heat perming improved wave efficiency, tensile strength, and hair cuticle condition compared to a base mist or no pretreatment, demonstrating the extract's protective effects against heat damage.

This study examined the drying of pomegranate peel as a method for reducing waste and found that drying efficiency varied with temperature and air velocity, potentially adding value to this by-product.

This study developed a polyherbal powder shampoo utilizing natural ingredients, with formulation F6 demonstrating optimal cleaning action and foaming index, along with satisfactory physicochemical properties, making it the preferred formula among the tested variations.

This study identified an optimal sulfate-free and silicone-free conditioning shampoo formulation using 1% hyaluronic acid at 800 kDa, 10% acidic sophorolipid, and 1% sodium chloride, which maintains essential conditioning and cleansing properties without compromising on performance.

This study explored the use of dexamethasone-loaded polymer hybrid nanoparticles in a xanthan gum hydrogel for treating alopecia areata, finding that freeze drying with sucrose influenced particle size, release, and permeation, but had no impact on cytotoxicity or anti-inflammatory efficacy in human keratinocytes.

This study found that heat preconditioning of nanofat from mice did not improve tissue vascularization or integration in grafting, and actually reduced vascularization due to increased expression of anti-angiogenic factors, suggesting it is not beneficial for enhancing its vascularization properties.

This article discusses the use of Espumil foam base in pharmacies for preparing dermatological medications and reports no new clinical results.

This study developed a rapid method to extract proteins from human hair, revealing phosphorylation on serine and threonine residues in alpha-keratins and matrix proteins.

Natural extracts like kombucha, marine enzymes, and prebiotics can improve and restore damaged skin.

The study concluded that the Exprecell™ device for preparing anticoagulant-free f-PRF increases volume yield and simplifies the process while maintaining biological activity comparable to conventional methods, suggesting potential clinical utility.

Adding keratin to a mix of cow hair and plant-based plastic makes it stronger.

Before hair restoration surgery, a thorough check-up is needed.

Three new techniques simplify and improve the preparation of tissue samples for skin cancer surgery.

Keratin can be successfully taken from human hair using a mix of choline chloride and ethanolamine.

This study found that hydrophobic amino acids from egg white hydrolyzed protein and L-phenylalanine effectively penetrate deep into the human hair fiber, increasing specific contents in both virgin and bleached hair.

In this study, the authors developed a modified alkaline-based proteomics protocol that improved the reproducibility of detecting hair proteins, potentially aiding future biomarker discovery.

In this clinical study, the use of potentiated zinc pyrithione shampoo improved scalp health and hair surface characteristics, suggesting that unhealthy scalp conditions may negatively impact pre-emergent hair's cuticle surface.

This study found that permanent wave treatment accelerates hair degradation after protease exposure, showing significant morphological differences compared to untreated hair and linked to damage from Alpha-helical region denaturation.

This study found that using a centrifugation speed of 1800 rpm for 10 minutes is optimal for preparing platelet-rich plasma with PRPBAG®, yielding an eightfold increase in platelet concentration.
