Hair+ Drip IV

How It Works

Hair follicle cycling is governed by the balance between anagen (growth, 2–7 years), catagen (regression, 2–3 weeks), and telogen (rest/shedding, 3 months). Nutritional deficiencies accelerate the premature entry into catagen and extend telogen, reducing hair density over successive cycles. Vitamin C (4000mg IV) is the obligate cofactor for prolyl hydroxylase and lysyl hydroxylase — enzymes that hydroxylate proline and lysine residues in procollagen, enabling the three alpha-chains to coil into the stable triple helix. Without this hydroxylation, collagen is structurally fragile and cannot form the basement membrane or connective tissue sheath that anchors hair follicles in the dermis. Vitamin C also regenerates oxidized glutathione (GSSG → GSH), amplifying the antioxidant protection provided by NAC. Magnesium Chloride (1200mg) is a cofactor for magnesium-dependent ATPases in follicle dermal papilla cells — the signalling hub of the hair follicle — and for the enzyme cystathionine beta-synthase that converts homocysteine to cysteine (the keratin structural amino acid). Magnesium also activates endothelial NOS (eNOS) to produce nitric oxide, causing vasodilation in the scalp microvasculature and increasing nutrient and oxygen delivery to the follicular dermal papilla. Dexpanthenol (B5, 1500mg combined) is converted to pantothenic acid and then to coenzyme A (CoA). CoA is the universal acyl carrier required for: (1) fatty acid synthesis in sebaceous gland cells for the protective sebum film around the hair shaft; (2) mitochondrial ATP production via the Krebs cycle in follicle stem cells; and (3) steroid hormone biosynthesis in the adrenal glands — cortisol excess is a primary trigger of telogen effluvium, and adequate B5 supports healthy HPA axis regulation. NAC (500mg) is the rate-limiting precursor for L-cysteine, which is in turn the rate-limiting precursor for glutathione (Glu-Cys-Gly). Follicular melanocytes produce melanin through a process that generates hydrogen peroxide as a byproduct — in ageing follicles, catalase activity declines and H₂O₂ accumulates, bleaching the hair and damaging follicle DNA. Glutathione (via NAC) is the primary defence against this follicular oxidative stress. NAC also directly supports keratin biosynthesis: keratin contains 14–18% cysteine by weight, and adequate cysteine supply is directly rate-limiting for hair shaft protein production. L-Carnitine (250mg) has been investigated specifically in androgenic alopecia: it upregulates the Bcl-2 anti-apoptotic signalling pathway in follicular keratinocytes, reducing the apoptotic cell death that prematurely terminates the anagen phase. Carnitine also ensures adequate mitochondrial fatty acid oxidation in the energy-intensive follicle dermal papilla cells. Biotin (50mg IV) activates four essential carboxylase enzymes — acetyl-CoA carboxylase (fatty acid synthesis), propionyl-CoA carboxylase (branched-chain amino acid catabolism), pyruvate carboxylase (gluconeogenesis), and 3-methylcrotonyl-CoA carboxylase (leucine catabolism). All four are critical for the lipid metabolism and energy regulation of rapidly proliferating follicle cells. Biotin deficiency causes alopecia, nail brittleness, and seborrhoea in animal models — IV delivery achieves tissue concentrations that oral biotin cannot match. Selenium (1mg) is the cofactor for glutathione peroxidase-1 (GPx1) — the primary enzyme protecting follicle cell membranes from lipid peroxidation caused by reactive oxygen species. Selenium also activates iodothyronine deiodinase, the enzyme that converts inactive T4 to active T3 thyroid hormone in scalp tissue — hypothyroidism is a major cause of diffuse hair loss, and local scalp T3 availability is critical for normal anagen progression.
