Hair goals? Meet your new routine hero. Vegamour has officially launched the Jumbo GRO Hair Serum—the same beloved, clinically tested formula, now in one ultra-convenient bottle. Starting April 3rd, fans of the #1 prestige hair serum can grab a 3-month supply in a single bottle, replacing the old 3-pack format (which is gracefully bowing out).

This plant-powered serum is more than just a pretty bottle. It's a daily essential for anyone looking to reduce shedding, combat thinning, and support visibly fuller, healthier hair, without disrupting your day. Lightweight, fast-absorbing, and scalp-friendly (no grease, no buildup, no drama), GRO is designed to work with your routine, not against it. The Jumbo GRO Serum makes the journey even smoother. No more juggling refills or cluttering your shelf with multiple bottles. Just one sleek, space-saving solution that delivers real results in as little as three months with consistent, regular use. 

Scroll below to shop the new Jumbo GRO Hair Serum and the rest of Vegamour's top-rated collection for haircare that fits your lifestyle — simple, effective, and stylishly streamlined.
