Hair loss or appearance of thinning hair can occur due to stress, aging, hormones, or even poor diet. Fortunately, hair fibers can help improve the appearance of your hair by adding volume to make it look fuller. The best part is that you can find the best hair fibers that look all-natural and do not have any adverse effects on your hair growth. 

Specific brands provide support for those with completely bald heads, while some require you to have hair in some spots for the product to thicken the look. 

In this article, we are going to review the following hair building fibers

What are Hair Fibers?

Hair fibers or hair loss concealers fill the thinnest spots of your scalp, giving you a thicker and fuller appearance. The fibers are derived from real hair, keratin, and cotton. You can find them in different colors to suit your hair color. 

All you need is an applicator to spread the fibers on your hair evenly.  The fibers will cling to your existing hair strands. Note that the fibers do not grow your hair, and they won’t work on large bald spots.  You should get hair fibers that consist of natural ingredients to avoid more hair damage. 

What To Look for When Purchasing Hair Fibers

Buying hair fibers can be tricky, especially if this is your first purchase. Below are some tips to help you choose the right hair fibers.

The Type of Hair Loss Concealer You Need

Hair building fibers are divided into three types, mainly powder, liquid, and sprays.  The sprays act like hair sprays. They have chemicals and color dyes that allow you to get a similar color shade like your natural hair.  Sprays are more popular than liquid concealers as they are simple to use and work well when you need to cover bald spots on your head. 

Sprays contain artificial chemicals and colors to match your existing hair.  Some spray formulas combine dyes and fibers to give you the desired results. They can be resistant to wind and rain, depending on the brand. 

Liquid concealers are available in cream and gel form and are stored in packets or tubs. 

Powder hair loss concealers work immediately upon application like hair loss concealer sprays.  They also have fibers that form a static electric bond with the scalp to give you a fuller and thicker look. 

You need to apply powder fibers generously to cover the bald areas.  Moreover, this formula gives you a more natural finish than sprays. You can find most of them in a shaker container to make the application easier. 

Check the Ingredients

You should only get the best hair fibers made of natural ingredients. Do not go for those that use harmful components or use preservatives like silica and paragon, as this could damage your hair. Keratin-based  products are also ideal as they consist of protein that’s similar to that of your natural hair. 

Cotton-based fibers give you a fuller look, but they do not stick to the hair as good as keratin-based fibers or natural human fibers.  Although it’s rare to find wool-based fibers, they are available in some hair concealers. Some people could experience some skin irritation, allergies, and immune reactions as the biological molecules of animals are different in structure from those of humans. 

Find the Right Color

Hair fibers are available in several colors to help you find a shade that appears natural and matches the color of your hair. Choosing a lighter shade gives you a powdery effect, and a darker shade may look too saturated or appear patchy. 

You can also mix different colors to make your hair pop. Start with the dark color and move to the lighter one when applying two colors. 

Understand Your Hair Type

Knowing your hair type is vital as you want to find a hair product that works for your  hair type. Some products work well for curly hair, while others are best for afro hair. Fibers that work on a variety of hair types are ideal. 

Find a Product That is Simple to Apply

The best thing about hair fibers is how simple they are to use.  However, you shouldn’t take any product and hope that it will work.  Avoid picking hair building fibers that have large holes in the shaker bottle or those that have a faulty pump. 

Choose Hair Fibers with Skin-Friendly Ingredients

Some products may trigger a skin reaction. If you have an autoimmune condition or you have a medical history of hypersensitivity, you should select a product with friendly ingredients to avoid these reactions. 

Opt for Hair Fibers that are Resistant to Environmental Factors

Nothing is more troubling than applying a hair concealer only for humidity to mess it up.  Get fibers that can withstand the influence of water, moisture, and heat. 

Consider Fibers That Can Adhere to Existing Hair

The right product should ensure that the fibers adhere to the existing hair through static electricity.  That ensures that the thinnest hairs become thicker. Avoid products that only cover the scalp but do not adhere to your existing hair, as this won’t give you a natural look. 

Also, you could end up with a less natural look if you apply the product to crew-cut hair as it will be challenging for the fibers to adhere to the scalp. 

Ability to Work on Every Hairstyle

The best hair fibers should work with any style,  whether you have short, curly, straight, or thin hair. Moreover, the hair loss concealer should be quick and simple to apply within seconds. 

Consider the Use of a Hair Fiber Applicator

A hair fiber applicator is a must-have accessory if you’re using keratin hair fibers.  All you need is to attach it to a bottle of hair fibers and use it on the thinning areas. Furthermore, the applicator allows you to  disperse the fibers evenly, thus creating a natural look. 

The tool fits a 28grams and 12 grams size hair bottles.  Make sure that you shake the bottle of the hair fibers when using the applicator to apply the hair fibers.  That allows the hair fibers to retain their loose structure.
