Biotin is also one of the Vitamin B complex necessary for fat and carbohydrate metabolism. It is essential for healthy skin, hair and nails and deficiency state has been shown to cause hair loss. [3]

Magnesium, an important mineral is essential for chemical reactions in the body including energy metabolism, protein synthesis, neuromuscular transmission, bone structure and hair growth. [4]

Zinc is an essential mineral necessary for a healthy immune system and proper functioning of enzymes. It is needed for cell division and hence important for skin, nails and hair. Studies report that zinc causes increase on hair density and reverses hair loss. [5] [6] [7]

Saw Palmetto extract has been shown to reduce DHT and 5 alpha-reductase. It actually blocks the receptor sites that are required for the absorption of DHT. It promotes hair growth by blocking the culprit DHT. [8] [9]

Nettle root blocks 2 enzymes, 5a-reductase, which makes the dihydrotestosterone (DHT) and aromatase enzyme, which makes estrogens. It also possesses antimicrobial, antioxidant, analgesic and antiulcer activity. [10] [11] [12]

Pumpkin (Cucurbita Maxima): The oil extract from pumpkin seeds has long been used as hair supplement. The extract has shown activity against testosterone, therefore has potential in preventing hair loss. [13]

Eleuthero Formerly Siberian Ginseng, (Glandular) is a member of the ginseng family, though it is of a different genus than other popular ginsengs such as the Panax variety. Like other ginseng, it had been traditionally used for healthy hair, for increasing endurance and helps restore concentration. The extract decreases testosterone levels in the body along with other stress hormones. [14]

Uva-Ursi extract has antimicrobial activity. [15] The herb neutralizes acidity in the urine, increasing urine flow, therefore reducing bloating & water retention, making it beneficial for hair growth.[16] [17]

Muria Puama plays an important role in energy metabolism, protein synthesis, neuromuscular transmission bone structure and hair growth for both men and women. Also help with stress management, nervous system stimulation, virility, and overall health. [18] [19] [20] [21]
