This study found that applying glycosaminoglycans fractions from ascidian tunics stimulated human follicle dermal papilla cell proliferation and, when used on mice hair for 28 days, produced a hair growth effect comparable to Minoxidil.

This review explores the eggshell matrix as a potential sustainable and cost-effective alternative source for glycosaminoglycans, but highlights the need for further research to enhance extraction techniques and economic viability.

Minoxidil boosts hair growth by undergoing a process in hair follicles and certain skin cells, and by increasing the production of compounds essential for hair growth and maintenance.

In this study, heparin was found to exert dose- and hair cycle-dependent effects on skin epithelial cells in mice, affecting hair follicle development and protein synthesis differently based on its administration method.

This study demonstrates the potential of infrared spectral imaging to assess hair follicle structures and heparan sulfate proteoglycan distribution across different phases of the hair growth cycle, offering promise for alopecia research.

In this study, growing human hair follicles in a defined glycosaminoglycan hydrogel ex vivo promoted cell survival, proliferation, and activation of hair growth-related signaling pathways, suggesting GAG-based hydrogels could modulate the hair follicle growth cycle.

Dog hair follicles contain important molecules that may affect hair growth.

This study found that glycosaminoglycan levels were higher in the occipital area of the hair shaft compared to the parietal area, with children showing higher levels than adults.

This review discusses the roles and mechanisms of glycosaminoglycans in wound healing and presents challenges and potential applications for GAG-based biomaterials without reporting new experimental results.

In this study, researchers developed a microfluidic-assisted technology to create dual-layer microspheres containing mesenchymal and epidermal cells, which efficiently induced hair follicle regeneration in mice, suggesting potential improvements for hair regeneration treatments in conditions like androgenetic alopecia.

This study found that combining microneedling with a topical glycosaminoglycan lotion improved hair density and follicular thickness in patients with androgenetic alopecia, with no adverse effects except mild pain, suggesting potential synergistic benefits as a treatment.

This study suggests that glycosaminoglycans, like hyaluronic acid obtained biotechnologically, are safe for topical cosmetic use, enhancing skin and hair conditions by supporting cell renewal, stimulating hair growth, and aiding in the treatment of scalp issues such as seborrhea and androgenetic alopecia.

This study found that the dermal glycosaminoglycan content and mast cell count in rats peaked during the anagen stage of hair growth and decreased during later stages.

In this study on wound healing, sulfated glycosaminoglycans from sturgeon cartilage enhanced fibroblast cell proliferation, migration, and collagen deposition, significantly accelerating wound closure and promoting re-epithelialization in both in vitro and in vivo tests.

This study found that N-acetyl-glucosamine-loaded nanostructured lipid carriers showed promise for skin lightening in healthy volunteers by reducing melanin distribution.

In laboratory settings, this study suggests that Serenoa repens and N-acetyl glucosamine with milk proteins may promote hair follicle vascularization through specific cellular interactions and actions.

This review discusses the diverse clinical manifestations of mucopolysaccharidoses in children and emphasizes the importance of early diagnosis and treatment initiation, but it reports no new clinical findings.

This chapter reviews hormonal imbalances and related disorders, discussing nutraceuticals—such as cod liver oil, green tea, and Omega-3s—that may alleviate symptoms and improve hormonal fluxes in lieu of traditional synthetic treatments that have potential side effects.

This study suggests that incorporating matrisomal components into biomaterials could enhance skin wound healing in mammals that do not naturally regenerate tissues like the axolotl and Acomys.

Some nutrients and antioxidants may improve skin and hair health, but more research is needed to confirm these benefits.

This study found that transcriptome profiling of cashmere goat skin revealed key genes and pathways involved in hair follicle initiation, differentiation, and maturation, which are critical for improving fleece production.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

This review discusses the impact of menopause-related oestrogen deficiency on skin ageing and suggests that oestrogen use may improve collagen and skin elasticity, but it reports no clinical trial results.

In this study, anabolic and catatoxic steroids were reported to prevent weight loss, tissue calcification, and cardiac necrosis in a rat model of disturbed calcium metabolism and progeria-like syndrome.

This article discusses the distribution of extracellular matrix molecules in human hair follicles and reports no new results.

This study found that dermal papilla and dermal sheath cells from human scalp tissue differ from interstitial dermal fibroblasts in morphology and produce varying levels of TGF-beta 2.

This review discusses the classic skin characteristics of hypothyroidism, notably generalized myxedema caused by increased glycosaminoglycan deposition, and reports no clinical results.

This study reports that adipose mesenchymal stem cell-derived exosomes and platelet-rich plasma both improved the condition of photoaged facial skin, with no significant difference in effectiveness between the two treatments, potentially offering a quicker and less invasive option for patients.

This study found no qualitative skin differences during development between mutant hairless USP mice and BALB/c mice, except for enlarged cysts in the hairless strain.

In this study, hydroxychloroquine treatment in patients with scleromyxoedema led to complete or partial remission of skin symptoms and improved mobility, though it did not affect paraproteinaemia.
