research dsRNA Released by Tissue Damage Activates TLR3 to Drive Skin Regeneration
Damage to skin releases dsRNA, which activates TLR3 and helps in skin and hair follicle regeneration.
research Penetration and storage of particles in human skin: Perspectives and safety aspects
Particles around 100 nm can penetrate and stay in hair follicles without passing through healthy skin, making them safe for use in topical products and useful for targeted drug delivery.
research K25 (K25irs1), K26 (K25irs2), K27 (K25irs3), and K28 (K25irs4) Represent the Type I Inner Root Sheath Keratins of the Human Hair Follicle
K25, K27, and K28 are found in all inner root sheath layers of hair, while K26 is only in the cuticle.
research A Novel Epithelial Keratin, hK6irs1, is Expressed Differentially in All Layers of the Inner Root Sheath, Including Specialized Huxley Cells (Flügelzellen) of the Human Hair Follicle
A new keratin, hK6irs1, is found in all layers of the hair follicle's inner root sheath.
research Follicular and percutaneous penetration pathways of topically applied minoxidil foam
Minoxidil foam enters hair follicles and skin for hair growth.
research Central centrifugal cicatricial alopecia
CCCA is a scarring hair loss condition mainly in African descent women, possibly caused by genetics and hairstyling, treated with gentle hair care and medications.
research Transcutaneous implantation of valproic acid-encapsulated dissolving microneedles induces hair regrowth
Tiny needles with valproic acid can effectively regrow hair.
research Stem cell quiescence acts as a tumour suppressor in squamous tumours
Inactive hair follicle stem cells help prevent skin cancer.
research Focus on Skin as a Possible Port of Entry for Solid Nanoparticles and the Toxicological Impact
Nanoparticles can enter the skin, potentially causing toxicity, especially in damaged skin.
research Preparation and characterization of dutasteride-loaded nanostructured lipid carriers coated with stearic acid-chitosan oligomer for topical delivery
The new dutasteride formula can be applied to the skin, may promote hair growth, and has fewer side effects.
research Influence of massage and occlusion on the ex vivo skin penetration of rigid liposomes and invasomes
Massage increases how deep both rigid and flexible liposomes can go into skin, with flexible ones going deeper, and covering the skin (occlusion) helps rigid ones more.
research Development of a Two-Dimensional Model for Predicting Transdermal Permeation with the Follicular Pathway: Demonstration with a Caffeine Study
Researchers developed a model that shows hair follicles increase skin absorption of caffeine by 20%.
research Methods for quantifying intrafollicular drug delivery: a critical appraisal
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.
research Frontal Fibrosing Alopecia: Role of Dermoscopy in Differential Diagnosis
Dermoscopy helps diagnose frontal fibrosing alopecia by distinguishing it from other hair loss conditions.
research Beyond goosebumps: Does the arrector pili muscle have a role in hair loss?
The arrector pili muscle might play a role in hair loss and needs more research to understand its impact.
research Hair Keratins and Hair Follicle–Specific Epithelial Keratins
Hair and follicle keratins differ in structure and expression, especially in cysteine content.
research Topobiology of Human Pigmentation: P-Cadherin Selectively Stimulates Hair Follicle Melanogenesis
P-cadherin is crucial for hair follicle pigmentation but not skin pigmentation.
research Cicatricial marginal alopecia: is it all traction?
Traction may not be the only cause of cicatricial marginal alopecia.
research From basal cell carcinoma morphogenesis to the alopecia induced by hedgehog inhibitors: connecting the dots
The article concludes that hair loss is a common side effect of drugs treating skin cancer by blocking the hedgehog pathway, but treatment should continue, and more selective drugs might prevent this side effect.
research Hair follicle-targeting drug delivery strategies for the management of hair follicle-associated disorders
New hair follicle-targeting treatments show promise for hair disorders but need more research on safety and effectiveness.
research The preventive effect of vitamin D3 on radiation-induced hair toxicity in a rat model
Vitamin D3 may protect rat hair follicles from radiation damage.
research Female Androgenic Alopecia
Women with low SHBG levels and a high 3a-diol G to SHBG ratio are likely to experience female pattern baldness, possibly due to a slight excess of androgens affecting sensitive hair bulbs.
research Biology of Human Hair: Know Your Hair to Control It
Understanding hair biology is key to developing better treatments for hair and scalp issues.
research The Increasing Importance of the Hair Follicle Route in Dermal and Transdermal Drug Delivery
Using hair follicles can improve skin drug delivery.
research A study of serial vertical sectioning of scalp biopsies to increase the histological diagnostic yield in alopecias
Cutting scalp biopsies in consecutive slices improves diagnosis of hair loss conditions.
research Cyclin-dependent kinase inhibitors, p21waf1/cip1 and p27kip1, are expressed site- and hair cycle-dependently in rat hair follicles
