The extra concentrated Aloe Vera, Rosemary extract, and vitamins and minerals in BOLDIFY's Hair Thickening Conditioner work in unison – removing DHT (the root cause of hair loss) and absorbing excess oil, then balancing moisture for a healthy, clean-feeling scalp that’s prepped for maximum strand retention.

THIN, FLAT, FINE HAIR WEIGHING YOU DOWN? BOLDIFY’s Hair Thickening Conditioner goes to work on contact, instantly infusing into your hair shafts and nourishing from the inside to banish breakage and thicken, strengthen and silken hair – for that full-volume look you want to see every day.​

Water/Aqua/Eau, Cetyl Alcohol, Stearyl Alcohol, Dicetyldimonium Chloride, Hydrolyzed Silk, Hydrolyzed Wheat Protein, Aloe Barbadensis Leaf Juice, Spirulina Platensis Extract, Rose Canina Fruit Extract, Panax Quinquefolius Root Extract, Centella Asiatica Extract, Panthenol, Methyl Gluceth-10, Arginine, Aspartic Acid, PCA, Glycine, Alanine, Biotin Serine, Valine, Salicylic Acid, Sorbic Acid, Proline, Threnine, Isoleucine, Retinyl Palmitate, Phospholipids, Sodium PCA, Histidine, Phenylalanine, Tocopheryl Acetate, Ascorbyl Palmitate, Glycerin, Fragrance/Parfume, Dimethicone, Hydroxyethylcellulose, Cetrimonium Chloride, Polyquaternium-37, Propylene Glycol Dicaprylate/Dicaprate, PPG-1 Trideceth-6, PEG-90M, Sodium Lactate, Sodium Hydroxide, Caprylyl Glycol, Decylene Glycol, Citric Acid, Sodium Benzoate, Phenoxyethanol.

BOLDIFY is committed to clean. Here are just three of the many power-packed body boosters included in our Hair Thickening Conditioner for their effectiveness, safety, and thickening properties.

BIOTIN

This 'Hair Food' vitamin is known to increase strand retention and reduce breakage for longer, stronger, & healthier-looking hair

SAGE

Sage is said to be highly beneficial for thinning hair due to natural oils that strengthen the roots and provide important nutrients to the hair follicles

ROSEMARY

Rosemary is known to help promote circulation in the scalp, and reduce premature greying and dandruff

We craft every bottle of BOLDIFY Hair Thickening Fibers in our GMP approved lab - without Animal Derived Ingredients or Harmful Artificial Preservatives – and we never test on animals. Rest assured you’ll see thicker hair from this NATURAL, EFFECTIVE, and SAFE product or we’ll refund you every penny – no questions asked.

  • Works great on Fine Thin Hair! I have fine thin hair and this product works perfectly. Not sticky or heavy, just makes my hair appear thicker !

  • Great Product and Fast Shipping: I have an undercut and I have Asian hair which means it is stiff, goes flat and not workable after it drys. This product gave my hair a much needed lift and stays in place after using hairdryer. It is a little sticky like what others have claimed but I like it because it stays the shape I need and with a little clay and hairspray, my hair stays in place and doesn't loose its shape throughout the day.

  • Wow Product. I love Boldify products. I'm 80 years old, yes it's a current picture, and my hair if fine. It takes a lot of products to get body and bounce... as far as making my hair full and lasting I love it.

  • No blow drying needed... this stuff is amazing! I don't need to blow dry my wavy hair for volume anymore!

  • I LOVE this! I previously used the Adria volumizing spray until I ran out and found this. Voluminous products are essential to me, because my hair is super thin, and straight. It's been a curse (I don't care what you thick, curly haired girls say, haha!) if you have the same trouble/ this product is for you! My hair is in the best shape of its life!
