If you suffer from thinning hair then you may have heard of hair fibers such as Caboki or Toppik.

Hair fibers, designed to enhance the volume and density of your existing hairline, are a simple solution for hair loss but they are not all created equal. Some hair fibers have a more natural look and feel whilst others are better designed for longevity and performance. Caboki is a common search result for hairloss fibers and has many plus points.

In this guide we take a look at Caboki hair fibers and answer some of the most commonly asked questions as well as giving you a review of the results you can expect.

What Are Hair Filler Fibers and How Can They Help with Thinning Hair?

Hair fibers are tiny fillers made from man-made or natural materials. Each fiber has an electromagnetic charge that occurs naturally depending on the material used. This charge reacts with the slightly positive charge of human hair causing the filament to temporarily bond. The effect is an increase in hair density.

They do not work with a fully bald head as they require hair to attach themselves to. Using them with a hairless scalp will result in a powdery finish that will not hold.

What is Caboki?

Caboki is an American company that produces a range of hairloss fibers and accessories. Founded in 2005 by a team of professional make-up artists, the products they create were originally supplied only for the stage and screen. An international company, Caboki has over 6 million customers and now sell their products to the general public.

Their customers are both male and female with some suffering from telogen effluvium, androgenic alopecia or simply age-related thinning of the hair.

The Range

Caboki produce hair fibers in a range of different sized containers in 14 color variations. The colors can be combined to blend a more natural match for your hair. The range comes with a variety of accessories including an applicator comb, panoramic mirror and control mist. They also sell a kit for applying fibers to your eyebrows.

All of the fibers used in Caboki’s products are sourced from 100% natural sources. The filaments are created from levant cotton which has a good negative charge. However, unlike fibers sourced from animals, cotton does not look, react or feel like human hair. The pay-off with stronger fixing in the Caboki product is a slightly less natural aesthetic.

How Do You Use Caboki Hair Building Fibers

Hair fibers can be applied to the hair in a number of ways and using a couple of different applicators; however, the most common method is a simple shake on approach. Caboki can be applied to existing hair in much the same way as you would season food, using the perforated lid of the hair fiber can. When the fibers come into contact with your existing hair, a bond is created between the positive charge of human hair and the negative charge of the filament.

The Caboki product range also includes a hairline perfector comb which allows you to create a more natural finish along the hairline itself.

Can You Use Caboki in all Conditions?

Caboki are confident that their hair loss fibers can withstand rain, wind and humidity. In reality, the results can vary depending on how severe the conditions you experience are. Most people who use Caboki find that daily wear-and-tear from normal weather is fine. However, some users find that the fibers ability to bond with the hair is severely diminished with excess moisture and wind.

How Long Do Fibers Last?

Caboki purports its products to last 200% longer than other fibers on the market and suggests that the fibers will remain in place until you shampoo your hair. And, no, you don’t need any special kind of shampoo.

In reality, fibers do work themselves free during the course of an application due to a number of reasons. The predominant cause of fiber loss is due to friction such as your head rubbing against a seat rest or during sleep on your pillow. Other factors can include environmental conditions such as excess wind and moisture and even a change in the electro-magnetism of the ambient surroundings.

Given that there are many factors at play when it comes to the longevity of any application, it is recommended that users carry a travel sized bottle of fibers so they can reapply if necessary. Many users who regularly go to the gym find that a workout can leave their hair fibers looking a little ‘flat’.

Can Caboki Hair Fibers Promote Healthy Hair Regrowth?

No. Caboki (or any hair filler fibers) do not promote the regrowth of hair nor do they prevent healthy regrowth. It is a concealer for hairloss that produces denser, fuller-looking hair. The use of hair filler fibers can be used in conjunction with topical treatments for hairloss, including Regaine, as well as supplements like Propecia. With topical treatments, it is recommended to apply these before using the fillers and to ensure that the scalp is dry before application.

Do Caboki Hair Fibers Actually Work?

The million dollar question…does Caboki actually work?

There is no question that the fibers supplied by Caboki do adhere well to existing hair and have a more durable bond than many other fillers on the market. The charge produced by levant cotton is well-documented in research studies to attach firmly and securely to human hair, outperforming other materials.

Whether others can tell that you are using Caboki is a question of just how honest your friends and family are. Remember that the original products were designed for the stage and screen where an audience is not as close to the focus of their attention as you are in real-life. The cotton material does not react like human hair and can look less natural than surrounding areas. So, you may not pass an up-close and personal inspection using Caboki particularly if you do not get a good color match for your existing hair.

However, the results do vary depending on how proficient you become in application, the extent of your natural hair loss and the color match. Many users report an extremely positive reception by other people whilst some find that they don’t quite manage to ‘pull it off’.

On the whole, most users are very satisfied by the look they can achieve using Caboki. Users on Amazon report the product as being 4.3 out of 5 stars with an overall positive rating of 75%. On Google Reviews the response is even better and, out of over 2000 reviews, the response is 92% positive.

This is a verified recent review of Caboki:

“No one knows you have it on. I really like it because I have lost about 50% of the hair on the front of my head and as a women it really shows being right up front. This does not add more hair, but it does help the hair I have to look fuller and to cover more of my bare scalp; which reduces the look of my pre-mature hair loss. It give me self confidence and that is huge. I do not wash my hair every day, as the more often you wash your hair the more you loose it. So I often sleep with the Caboki powder left on. It does not rub off on my pillow or sheets. But if you sweat a lot (such as at the gym) or if your head gets wet it will run and will need to be re-applied. It works best if you keep just back from the edge of the hair line.”
