Support thicker, fuller hair from the inside out with Force Factor Hair Growth Accelerator Pro — an advanced hair growth supplement formulated with four clinically studied ingredients and essential vitamins, minerals, and antioxidants for complete hair, skin, and nail support. It’s powered by Lustriva, a patented biotin-silicon complex that’s 40X more soluble than standard biotin and clinically studied to increase hair thickness starting in as little as 3 weeks.* Force Factor Hair Growth Accelerator Pro is the only supplement that combines Lustriva with three additional clinically studied ingredients — Cynatine HNS, Shoden Ashwagandha, and Serevelle saw palmetto — for a complete, multi-targeted approach to hair health. Cynatine HNS delivers 500mg of solubilized keratin per serving to help reduce shedding and breakage, and support stronger, shinier strands. Serevelle made from saw palmetto, the #1 dermatologist recommended natural ingredient for hair growth^, is a proprietary extract standardized to 55% fatty acids that helps support new hair growth and support a fuller hairline. Shoden Ashwagandha helps balance internal factors that impact hair health and resilience throughout the hair cycle. Together, these four powerhouse ingredients address hair growth, density, strength, and shedding — all in one daily serving of 3 capsules. Force Factor Hair Growth Accelerator Pro is made in the USA in GMP-certified facilities, with every ingredient rigorously tested for potency and purity. Just one serving per day delivers targeted, science-backed nutrition to help you look and feel more confident. *In a clinical study by Kalman et al. (2021) on 90 female subjects with self-reported hair thinning, those taking 160 mg of Lustiva® per day experienced a significant increase in hair thickness at week 3 compared to placebo, as seen by an improvement in the ratio of percent vellus (thin) to terminal (thick) hair. ^Based on an IQVIA ProVoice Survey fielded to physicians from June 1, 2024 through May 31, 2025, saw palmetto is the #1 dermatologist-recommended, clinically studied bioactive ingredient for hair growth.
