This study found that an extract treatment showed similar efficacy and tolerability to calcipotriol/betamethasone ointment in reducing psoriasis severity and symptoms over 28 days in patients with mild-to-moderate plaque psoriasis.

This study found that applying pet ether extract of Brassica oleracea to rats' skin promoted earlier and longer anagen phases in hair growth, outperforming 1% minoxidil.

This study found that combining 7% chamomile extract with 5% minoxidil solution may reduce cutaneous side effects like itching, scaling, and erythema in male patients with androgenic alopecia, potentially improving treatment compliance.

Sea holly extract may help reduce hair loss.

The study found that safflower extract may help protect human follicle dermal papilla cells from cisplatin-induced damage, suggesting its potential as an adjuvant in chemotherapy to mitigate hair follicle cell damage.

This study investigated a herbal hair lotion using natural ingredients like rosemary and fenugreek extracts, finding that the F3 formulation had optimal spreadability, absorbency, washability, and stability, without causing skin irritation.

This study found that de-saponinated Camellia seed cake extract promotes hair growth in vitro and in vivo by enhancing dermal papilla cell proliferation and modulating signaling pathways and growth factor expression.

Pink berry extract effectively treats scalp issues from frequent head covering.

This study found that Datura metel extracts obtained through supercritical CO2 extraction demonstrated significant biological activity, including antioxidant and anti-inflammatory properties, and effectively promoted wound closure and collagen preservation, comparable to standard treatments, in laboratory experiments.

This study suggests that Medicago sativa extract, combined with UVA light, may enhance pigmentation in hypopigmented skin and hair, offering potential treatment for vitiligo.

In this study, Myrtus communis leaf extract significantly reduced IL-1α expression and increased VEGF expression in human keratinocytes, which the researchers suggest may be linked to its traditional use in treating hair loss and wound healing. Further investigation is needed to clarify its mechanisms.

This paper highlights the growing scientific interest in plant extracts for cosmetics due to their potential benefits, including antioxidant, antimicrobial, and protective properties, while emphasizing the need for quality and safety assessment to mitigate possible adverse reactions.

This study suggests that a topical emulsion containing Camellia sinensis and Allium cepa extracts may show promise for treating alopecia areata in Wistar rats.

This study formulated a nanogel with Bangkal bark extract that showed moderate antibacterial activity against Propionibacterium acnes, with the F3 formulation (8% extract) achieving the highest inhibition zone of 8 mm, suggesting potential as a natural acne treatment.

This study found that the ethanolic extract of Acanthus ebracteatus demonstrated potential as an anti-hair loss treatment by promoting dermal papilla cell proliferation, inhibiting 5α-reductase activity, and reducing inflammation in vitro.

This study developed EGCG-loaded nanohydrogels using ethyl cellulose and polyvinyl alcohol to enhance the stability and delivery of the hydrophilic drug in aloe vera gel, optimizing encapsulation efficiency and drug release properties.
