This review highlights the benefits of henna (Lawsonia inermis) as a natural and safer alternative to synthetic hair dyes, which can cause skin irritation and other health issues. Henna's active dyeing component, lawsone, binds to hair keratin, providing an orange-red to brown color. Combining henna with other herbs like indigo, amla, and hibiscus can enhance color variety and appeal. While henna is safer, it has limitations in shade range and stability. The review emphasizes the need for standardized evaluation and safety assessments, and suggests future research should explore advanced formulations and clinical validation to establish henna as a globally accepted hair dye. Regulatory guidelines for herbal cosmetics are currently inconsistent worldwide.

This study investigates non-dermatophyte moulds in dogs and cats with mycotic dermatitis, highlighting their role as opportunistic pathogens in dermatological disorders. Skin and hair samples from affected animals were cultured and examined, identifying moulds such as Aspergillus spp., Penicillium spp., and others. The study emphasizes the importance of traditional mycological techniques for identifying these moulds and provides baseline data on their occurrence and diversity, aiding in better diagnosis and future research in veterinary dermatology.

The study optimized in vitro culture methods for human epidermal stem cells (EpSCs) using different media and supplements. Explant culture in MEM-α with 20% FBS initially showed promising cell attachment but lost morphology by passage 1, while suspension culture with MEM-α and growth factors yielded more EpSCs. EpiLife media with KGF, EGF, and HKGS supported proper EpSC attachment and morphology. EpSCs cultured in MEM-α and EpiLife with growth factors demonstrated high proliferation and clonogenic potential, expressing markers like p63 and KRT5. These findings suggest that EpSCs cultured under these conditions are suitable for skin regenerative medicine.

The review explores the use of herbal drugs, specifically Hibiscus rosa-sinensis, Allium cepa L (onion), and Aloe vera, for promoting hair growth, particularly in cases of androgenic alopecia. These herbs are noted for their ability to block dihydrotestosterone (DHT), a key factor in hair loss, and enhance the anagen phase of the hair cycle. Hibiscus rosa-sinensis has antioxidant properties that protect hair follicles, onion provides sulfur and antibacterial benefits for scalp health, and aloe vera contains vitamins and compounds that repair hair strands. The review suggests these herbal treatments as promising alternatives to conventional medications like Minoxidil and Finasteride, which have limitations and potential side effects. Additionally, the psychological impact of hair loss and the importance of addressing stress and hormonal imbalances are emphasized.

A case study of a 28-year-old female with alopecia areata showed that individualized homoeopathic treatment using Phosphorus 200 led to reduced hair fall and visible hair regrowth over a three-month period. While the patient experienced clinical improvement, the study's findings are limited to this single case, and further research with more participants is necessary to determine the broader effectiveness of homoeopathy for treating alopecia areata.
