Features

  • HAIR THICKENER SPRAY: Our Kerotin Extensive Solution is a lightweight, diameter-boosting hair spray that can help with hair loss. It works to penetrate the hair fiber to increase thickness over time while nourishing and restoring strands.
  • PERFECT FOR HAIR CARE: This is the perfect all-in-one hair spray that every woman needs! The hair repair spray uses botanicals and polymer technology to increase hair thickness, strength and resistance over time, reducing breakage and shedding. The product can also provide moisture, movement, heat protection, and damage repair.
  • NATURAL INGREDIENTS: Our thickening mist spray is formulated with natural ingredients to deliver you the best results. Our key ingredients include Amaranth Extract which can boost hair thickness and strength, Hibiscus Extract which works to condition against dryness and damage, reducing frizz, split ends and breakage, and Baobab Protein which can improve strand elasticity, as well as act as a heat protector for hair.
  • EASY TO APPLY: Apply the hairspray daily over the entire length of hair, from root to ends, to increase thickness over time while nourishing and stimulating hair growth. Best suited for fine, weak, and thinning hair. For instant volume, combine with the Kerotin Volumizing Line (visit our Brand Store to shop all products).

  • Good and Bad..............
Size: 4 Fl Oz (Pack of 1)
So I don't know if its my hair, my shampoo/conditioner, or styling product but when my hair is wet, trying to brush my hair is impossible which is a bad bad thing for my thin fine hair. It's almost "sticky" so if I have to style my hair by blow drying it - this product is a "no" for me. However, once dry, my hair can easily be brushed and does FEEL fuller. So on the day's I don't need to go anywhere and can just let it air dry, it's fine. Having said all that, jury is still out whether it actually makes my hair thicker or if it's just the product filing it out. ... show more

  • Love this product
Size: 4 Fl Oz (Pack of 1)
I love this thickening spray. It makes my hair look so full and I get great volume. My hair is very fine but when I use this it looks very thick. It also protects your hair from hot styling tools. I highly recommend this product and will never be without it.

  • Not great
Size: 4 Fl Oz (Pack of 1)
This doesn't really thicken very well, and if you use too much of it, it makes your hair dry and a little brittle feeling. It didn't work for me. The scent is not heavy, but it's also not a pleasant or nice scent either. It dissipates quickly, but I don't like it while I'm spraying it.

  • This actually works
Size: 4 Fl Oz (Pack of 1)
I am one of those women obsessed with her hair. I’m 60 years old and my hair is half way down my back. It’s not super pretty hair, kind of medium textures, but still looks OK for my age. I started using this spray about two weeks ago, and I was gob smacked, as they would say in Australia. It’s really works. It makes my hair a lot sicker without stickiness weighing it down. I used ones on damp hair and ones between washes, every 3 to 4 days. It just looks like I have more hair. It feels thick and just beautiful. I assume that one bottle will last me about 5 to 6 weeks and I will make sure to have this on hand for the rest of my hair life. ... show more
