Allium sativum (Garlic) Bulb Extract is a botanically derived active characterized by a rich composition of organosulfur compounds (notably allicin, ajoene, diallyl sulfides), alongside flavonoids, saponins, vitamins (B-complex, C), and trace minerals. These constituents impart pronounced antioxidant, antimicrobial, and anti‑inflammatory activities, making garlic extract of interest in cosmetic formulations targeting acne‑prone, stressed, or environmentally challenged skin. Mechanistically, allicin and related sulfur compounds inhibit the growth of pathogenic microorganisms while modulating inflammatory mediators such as TNF‑α and IL‑6, thereby contributing to reduced erythema and microbial imbalance on the skin surface. In addition, garlic extract demonstrates free‑radical scavenging capacity and protection against lipid peroxidation, supporting barrier integrity and helping limit oxidative pathways associated with premature skin aging. These properties justify its inclusion in clarifying serums, purifying masks, anti‑blemish creams, and protective daily skincare products.

In haircare and scalp formulations, Allium sativum Bulb Extract is primarily valued for its antimicrobial and circulation‑supportive effects, which can help maintain a healthier scalp environment and reduce dandruff‑associated microorganisms. Experimental and clinical observations suggest that garlic‑derived compounds may stimulate microcirculation and follicular metabolism, indirectly supporting hair vitality and fiber strength. Its antioxidant and anti‑inflammatory actions further assist in mitigating scalp irritation caused by oxidative stress, surfactants, or environmental exposure. Consequently, garlic extract is incorporated into scalp serums, strengthening shampoos, hair masks, and botanical tonics formulated for weak, thinning, or imbalance‑prone hair types.
