BOLDIFY 3-in-1 Hair Thickening Serum contains Biotin to enhance strand retention and promote strand strength, minimizing hair loss due to breakage and excess fall.

While most hair serums leave your hair feeling sticky, flat and dull, BOLDIFY supports that “fresh from the salon” Brazilian blowout look, without the tacky feel. Plus, it smells delicious!

PROVEN RESULTS

Step 1

Squeeze a dime-size amount into your palm. (Less is more!)

Step 2

Work through hair with fingers, starting with the ends and working your way to the roots, stopping just short of the scalp.

Step 3

Blow dry on medium/high heat for incredible healthy fullness and all-day body!

BOLDIFY is committed to clean. These three power packed body boosters are included in our Hair Boost Serum for their effectiveness, safety, and volumizing properties that not only work instantly, but ensure longer, stronger, healthier-looking locks long-term.

Biotin

Widely known as the 'Hair Growth Vitamin', Biotin can help thicken hair over time by reducing breakage and fall, and supporting strand retention.

Coconut Oil

Coconut oil is a natural way to help your hair get longer and thicker, faster. The vitamins and essential fatty acids naturally found in coconut oil nourish the scalp, and help to remove sebum build-up from hair follicles.

Lemongrass Extract

Essences of lemongrass can help protect hair follicles from oxidative stress, promoting optimal function and healthier-looking locks.

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!
