2018 Reviews on the Best 6 Hair Building Fiber Concealers


Hair loss (or Alopecia) is a medical problem that doesn’t care about race, skin type, gender or even age. It is believed that you may commonly experience hair loss at an old age, but according to the American Hair Loss Association,[1] 25% of men in the US start losing their hair by the age of 21 and women make up to 40% of American hair loss sufferers. Even children can suffer from this disease.

There are multiple causes for losing your hair.[1] Hair loss is hereditary in most cases, but there can be other reasons why your hair is losing its texture and eventually fall: diseases, medicine, menopause, childbirth, stress, diets, lack of vitamins, the same hairstyle for years or certain hairstyling products.

When hair loss is permanent, the treatments usually imply expensive medical remedies and surgical methods such as hair transplants. Luckily, the market offers a solution for covering bald spots and receding hairlines at a more affordable cost and by creating the effect of a natural thicker hair look: Hair Building Fiber Concealers.

Research on hair fibers is a must before buying

Types of hair building fibers

Hair building fibers are small hairs that, once applied on the problematic areas, bind to your existing hair like little magnets. The small static charges between the fibers and your hair create a strong firm bond. This makes the effect of thick full hair last longer and appear more natural.

Natural human hair fibers are the most appropriate option to your natural hair. It is a safe material and successfully covers baldness and thinning hair. There is nothing more natural than real human hair.

Keratin is a fibrous organic protein and a main structural constituent of human hair and skin. Therefore, Keratin fibers effectively cover bald patches without irritating the scalp. Since hair is already made of keratin, an artificial look when using keratin hair fibers is completely out of the question.

Cotton fibers (usually made out of moroccan cotton) is also an ingredient that easily sticks to your hair creating a full head look since it has a negative charge. The only problem is cotton sticks only to existing hairs, so it is more effective on thinning areas than on bald patches or completely bald scalps.

Wool (or any other animal product) fibers are another way of making your hair look thick, but is better to be avoided. Animal hair structure is different from ours, so wool is an ingredient that will not conform to all hair types and also you might find yourself experiencing allergies or irritations.

Common concerns when using hair fiber concealers

Hair concealing products come in many forms and sizes. Sprays are easy to use, but, usually, contain color chemicals and just give your scalp a dyed shade, creating an artificial look if not used properly. In the last years, people have gone towards powder concealing products made out of natural keratin fibers that electrostatically stick to your existing hair.

Top brands of hair fiber concealers constantly improve their products. They cover a large range of colors, they work for any type of hair and the best ones don’t wash away from sweat or rain and don’t blow in the wind.

People worry about getting their clothes or face dirty and some are afraid that combing their hair might ruin the effect. Natural fibers are meant to stick to your hair, not to your skin or clothes.

What to look for when buying a hair fiber concealer

Finding a hair concealer that suits you is a matter of trial and error. However, it is easier and faster to find that one concealing product if you take into consideration a few important aspects before buying.

Your hair concealer must contain natural organic hair fibers. Keratin hair fibers or human hair fibers are the closest to what our hair is made of and they will blend naturally with any type of hair, avoiding an artificial look. No one wants to draw attention to their problem.

Your hair fiber concealer must be easy to apply. Good hair fibers work instantly, must not require a lot of hassle and go off only with regular shampoo. You have to be able to apply it quick even when you are not in a hurry.

Most hair building fiber concealers offer a variety of colors and shades. Make sure you choose the right color. It’s frustrating to draw attention to your bald patches just because you used the wrong shade. If you are not sure about the color just order the smallest option the brand has.

Reviews from other customers can help you a lot when buying a hair concealer. Amazon, for example,  has eliminated reviews given in exchange of a sample or a discount and verifies each purchase linked to a review. That way you can find only real men and women suffering from hair loss and sharing their experience with the product.
