In this study, researchers applied Yashtimadhwadi tail using shirodhara and Nasya karma treatments on sixty patients experiencing hair fall, finding that both methods produced excellent results in reducing symptoms such as hair fall, roughness, and dandruff.

This study experimentally validated Lockhart's viscoplastic framework for tip growth in Arabidopsis root hairs by demonstrating alignment with observed growth rates and estimating yield turgor pressure and cell wall viscosity, offering a methodology adaptable to other species and conditions.

This report describes a case where dermoscopy of shed hair helped diagnose post-COVID acute telogen effluvium by revealing depigmented club-shaped bulbs, highlighting its potential as a noninvasive diagnostic tool.

This study showed that in C3H/HeJ mice, focal follicular inflammation starts before overt hair loss, with inflammation severity possibly reaching a threshold causing hair follicle dystrophy prior to visible hair loss.

This study found that betamethasone increased tyrosinase activity and melanin content in amelanotic melanocytes from human hair follicles, suggesting a potential mechanism for glucocorticoid treatment in vitiligo.

In Arabidopsis thaliana, this study found that proper O-glycosylation of extensins is crucial for root hair elongation and self-assembly of the cell wall.

AGD1 is important for root hair development in Arabidopsis, working with phosphoinositide signaling and the actin cytoskeleton.

This study found that involucrin likely plays a key role in forming the cornified material of the medulla and inner root sheath of human hair, contributing to its mechanical strength.

In this study using C57BL/6 mice, researchers found that iron oxide nanoparticles permeated skin primarily through hair follicles and sebocytes, with absorption increasing over time.

This study identified significant differences in medullary structure, hair length, and root diameter among dorsal guard hairs of red foxes, golden jackals, and gray wolves in Turkey.

In this study, autophagy was commonly observed during keratinization in neonate rat hair follicles, suggesting lysosomal proteases and cytoplasmic enzymes may coordinate in hair follicle cell differentiation.

This study concluded that epidermal growth factor may induce a 'catagen-like' phase in human hair follicles by disrupting normal cellular proliferation and migration patterns.

In this study, researchers found that the curliness of human hair is associated with an asymmetric structure at the cellular level, particularly in the differentiation of the precortex.

This study visualized mitochondrial metabolism in cultured bovine hair follicles and plucked human hairs, finding that ROS and mitochondrial polarization correlate in specific hair follicle regions, particularly near keratin deposition sites.

This study developed an in vitro model using human follicular keratinocytes to observe selective cell growth and differentiation, potentially aiding future research on hair biology and growth processes.

This study suggests that the structure and function of the inner root sheath in mammalian hair may have evolved from simpler forms seen in monotremes, aiding in hair exit without damaging the epidermis.

This study reports that 0.025% tretinoin lotion seemed effective for idiopathic hair casts in two young girls and suggests an infrainfundibular origin for the lesions.

Hair proteins change location and structure as hair cells mature.

This study explored the structure and keratin composition of marsupial hairs, finding similarities in keratin localization to hairs in placental mammals, and highlighting potential roles of trichohyalin and transglutaminase during hair development and shedding.

In this study, two cases of idiopathic hair casts in young girls responded well to 0.025% tretinoin lotion, with analyses suggesting an infrainfundibular origin for the lesions.

This study found that in human hair bulbs, telomerase is present mainly in the nuclei of cells undergoing proliferation, particularly in the matrix epithelium during the anagen phase, and sparsely in the outer root sheath during late catagen and telogen phases.

In this animal study, pigs on a biotin-deficient diet showed significant hair loss, weak and brittle claws, and skin lesions after 8–10 weeks, with tissue necrosis observed microscopically after 15 weeks.

In this study, researchers observed that trichocytic and epithelial cytokeratins have distinct expression patterns within various human and bovine hair follicle cells, contributing to understanding hair follicle development and growth.

Keratin patterns in hair follicles help understand hair growth and potential hair and nail disorders.

This study found that expression of certain mutant keratin genes in mice led to severe alopecia, suggesting a similar mechanism could cause hair loss in humans.

This study found that distinct hair fiber structures among blue fox, mink, and otter rabbit can be used to identify and differentiate these fur types.

This correspondence describes two patients with both epidermolysis bullosa simplex, Dowling-Meara type, and loose anagen hair syndrome, an association not previously reported in the literature.

This study found that Arabidopsis thaliana mutants with altered AtRBOHC/RHD2 enzyme function showed abnormal protein regulation linked to increased drought sensitivity due to disrupted plasma membrane protein balance and cytoskeleton changes, as revealed through proteomic analysis and advanced microscopy.

In this case report, a 35-month-old girl with loose anagen hair syndrome experienced spontaneous resolution and hair regrowth within 24 months.

This study used a multi-point tension test method to evaluate hair damage over time and found it useful for assessing the effects of cosmetics and metal content on hair strength.
