See the difference for yourself. When Caboki fibers are exposed to flame, they smell like burning cotton cloth — a sign of their natural plant-based composition. Many other brands release a harsh plastic-like smell instead. It’s a simple test that reveals a very noticeable difference in materials.
Caboki is safe for your scalp, feels light, comfortable, and itch-free all day. It blends seamlessly with your existing hair for a completely natural, undetectable finish — and washes out easily with shampoo. That's why professional hair stylists prefer Caboki.
Caboki Hair Building Fiber is available in 14 colors. Pick a color that matches your hair.
How to select a color?
Stand in front of a mirror, check the hair ROOT color in the thinning area. This is the color to match.
If you have salt & pepper or highlighted hair, match the darker ROOT color. For example, if your native hair color is dark brown with some grey hair or highlighted hair mixed in, choose our Dark Brown.
Can Caboki hair fiber cover gray roots?
Yes, Caboki hair fiber can help blend in both gray roots and color-treated root re-growth.
Caboki hair fiber is made of Gossypium Herbaceum (Levant cotton) fiber, mineral colorants (Iron oxide).
Caboki hair fiber is easy to use:
In general, it takes no longer than brushing your teeth in the morning.

"I am 86 and suffering from pretty severe hair loss in the front and crown. I have taken supplements meant to help and they have I suppose but nothing noticeable. I was so happy you had the free trial size available. That is what caught my attention. I tried it and I love it. The front of my head shows no hair loss at all and the crown is greatly improved! I am a believer and this is one product I will happily tell others about!"
"This is the best of this type of product available. Works exactly as described and there was no craziness involved in getting the sample (no leaving a credit card number and having me cancel a subscription, etc. ,). I truly appreciate the process of getting the sample was exactly as described, pay one time for shipping and that’s it! This is a great way to do business when you have an amazing product. Get it to the people and they will come back! I’m definitely going to be ordering the full size of this product because I have tried EVERYTHING."
"The prodult doesn't look bad, just doesn't stsy in very good. Even setting it with hairspray"
"It was interesting and worked way better than I thought it would. I followed the instructions exactly and I was surprised that my "scalp" areas immediately seemed to disappear. I need to use it more to see how it does overtime."
"The sample sent to me matched my hair perfectly . At first I wasn't so sure about the whole tapping it into my hair but as you can see by the pics it works,"
"I have used another brand before but I prefer this Caboki. I think the color looks more natural and matches my hair better. I chose the salt & pepper dark. It is pricy though."
"I tried the product and my hair looks thick and natural. I tried practically all different products and they all failed because some of them only covers your scalp and it looks like your scalp is painted black not like Caboki the fiber sticks to your hair making it looks like you have thick strands of hair"
"I am a long time user of hair fibers, but this is the first time I tried Caboki. My hair is light medium brown with a touch of grey in it. The other hair fiber product I was using (Toppik), is very much a reddish brown. Caboki is a much better color match! Coverage is quite natural too. Very happy here!"
"I am beyond impressed with Caboki hair fibers! It blends so naturally with my hair and instantly covers my thin and balding areas without looking fake or powdery."
"I was happy with the results, and the color match. Unfortunately, it is much too expensive for my budget."
