General Hair Loss

Alterations in the scalp microbiome, particularly enrichment of Cutibacterium acnes and Malassezia, may contribute to AGA pathogenesis via lipid-immune interactions, suggesting potential benefit from lipid-modulating agents such as ketoconazole.

Microtrauma-based treatments like microneedling, lasers, and PRP increase hair density and thickness in androgenetic alopecia and promote regrowth in alopecia areata.

Topical actives like Redensyl and Procapil show promising results, often in combined formulations, but clinical evidence is limited by small sample sizes and lack of standardized comparisons.

A consensus of experts identified seven recommended interventions for AGA, including oral and topical finasteride, dutasteride, and minoxidil, while identifying 17 interventions that are not recommended.

The review identifies topical melanin stimulants, antioxidants, dietary supplements, and LLLT as promising approaches for managing gray hair.

The review highlights that while FDA-approved treatments are limited, natural supplements like saw palmetto and pumpkin seed oil show promise in inhibiting 5-alpha-reductase and promoting hair density.

Scalp cooling is the current standard for preventing chemotherapy-induced alopecia; minoxidil, photobiomodulation, and PRP are used to promote hair regrowth, though supporting evidence varies.

Regenerative medicine showed up to 68.4% improvement in androgenetic alopecia and up to 71% improvement in vitiligo across the reviewed RCTs, indicating promising efficacy for these dermatologic disorders.

Micronutrients play a role in the hair follicle cycle and immune function, and deficiencies may be modifiable risk factors for alopecia, though large-scale trials are needed.

A combined rosemary and neem extract (2:1) demonstrated superior antifungal activity against dandruff-causing agents compared to ketoconazole and outperformed minoxidil in hair growth trials.

Several natural ingredients including saw palmetto, pumpkin seed oil, melatonin, caffeine, and rosemary oil showed effectiveness in treating AGA compared to baseline or minoxidil.

The review summarizes the potential of various herbal compounds, specifically highlighting rosemary oil as a promising natural alternative for managing androgenetic alopecia.

The paper outlines standard treatments for different alopecia types, noting minoxidil as first-line for androgenetic alopecia and various therapies for focal hair loss.

Chemotherapy-induced alopecia affects approximately 65% of patients; current FDA-cleared prevention is limited to scalp cooling, while regrowth options include minoxidil, PBMT, and PRP.

Medicinal plants and natural compounds show potential in promoting hair growth and preventing alopecia through anti-inflammatory, antioxidant, and metabolic improvement properties.

Traditional treatments like corticosteroids and minoxidil have limited efficacy and high recurrence rates, while new strategies like JAK inhibitors and biologics are emerging.

Injectable PRF yielded favorable outcomes in androgenetic alopecia, periorbital rejuvenation, as a temporary filler, and for wound healing.

Hair loss is common after sleeve gastrectomy, typically occurring between months 3 and 4. Biotin supplementation shows low efficacy in reducing hair loss regardless of biotin deficiency status.

The review discusses the pathophysiology and various emerging treatments such as microneedling, LLLT, and autologous fat transfer for female pattern hair loss.

Current treatments for alopecia areata lack proven long-term effectiveness for all patients and are prone to relapse. JAK-STAT inhibitors and PRP are identified as promising future therapies.

Topical tretinoin for 5 days converted 43% of predicted minoxidil nonresponders to responders by upregulating follicular sulfotransferase.

Discontinuation of infliximab combined with oral minocycline and topical therapies led to complete resolution of alopecia within 4 months.

The review identifies 23 medicinal fungi or plants with potential anti-androgenic, anti-inflammatory, or vasodilatory effects that may improve hair growth in androgenic alopecia, though clinical efficacy data vary.

Herbal drugs may reduce hair loss by inhibiting the 5-alpha-reductase enzyme with potentially fewer side effects than conventional pharmacological treatments.

The review concludes that while biologics can alter or slow hair aging, none can reverse the natural course of hair loss or graying.

Zinc deficiency is linked to various skin conditions, including alopecia and impaired wound healing, suggesting that adequate zinc levels are important for skin health.

The review highlights several emerging therapies, including novel excipients for oral minoxidil, dutasteride, and finasteride; topical prostaglandin modulators; low-level laser therapy; Wnt pathway activators and stem cell treatments for androgenetic alopecia; JAK inhibitors for alopecia areata; antiandrogens and pioglitazone for frontal fibrosing alopecia; and robotic-assisted follicular unit extraction for hair transplantation.

Early initiation of treatment and combination of multiple modalities are suggested to be more effective than monotherapy for reducing hair loss and promoting regrowth.

The paper discusses treatment options for canine hyperadrenocorticism, including surgical removal of adrenal tumors and medical therapy with mitotane or ketoconazole.

The paper discusses tinea, a fungal infection, and does not evaluate hair loss treatments.
