Triple-Action Formula For a Light, Voluminous Finish: Unlike hairspray for fine hair, curlers for fine thin hair, and other multi-product hair care treatments, BOLDIFY's Biotin Hair Serum weightlessly acts as 3 products in one - hair vitalizing serum, leave-in conditioner, and plumping volumizer - to give you that "fresh from the salon" blowout look and feel - WITHOUT damaging buildup and greasy, sticky residues that leave locks limp and lifeless. Make Gorgeous Blowouts a Breeze: Squeeze a dime-sized amount of serum into your palm (more for longer hair), and rub hands together; apply evenly through clean, towel-dried hair, starting at the ends and working toward roots, avoiding the scalp. Style as usual by allowing hair to air dry for soft, natural fullness, or blow-dry for 3X more volume! Either way, our leave-in conditioner plumps and nourishes strands for a phenomenally full, superiorly silky style. Your Satisfaction Promise: As trusted hair thickening and volumizing specialists and a leader in thin hair care, we want you to try our root lifter hair products and love them - 100% risk-free! We promise that BOLDIFY's cruelty-free 3X Hair Serum will promote gorgeous, lustrously shiny, thicker, longer, stronger hair - or we will refund you the purchase price upon request. No questions asked, no return required!. Dry, Tired, and Dull Looking Hair? Our hair volumizer for fine hair provides vital nutrients for happier follicles, promoting strand retention & inhibiting breakage. With each use, BOLDIFY nourishes, plumps, and strengthens hair - working to reverse existing and prevent future damage - for thicker, longer, stronger, shinier locks. With such a light feel and a delicious scent, you'll look forward to using it after every wash! It's truly one of the best root lifter hair products for fine hair. Enhanced appearance from the first application: Our natural, non-greasy hair nourishment and volumizer complex is infused with biotin for maximum benefit, making it one of the best hair accessories for women! This hair thickener for fine hair women absorbs into and seals follicles, nourishing from the inside out for instant volume and shine - for men & women alike.
