What are Hair Fibers?

Hair fibers are tiny static-charged strands made from keratin. Also known as hair building fibers, these sprays and powders work quickly to fill in thinning hair and cover bald spots.

Hair fibers give the appearance of thick, full hair by bonding to hair follicles using static electricity and keratin. Available in spray or powder form, the best hair building fibers look identical to an individual’s natural hair, no matter if it’s straight or curly.

With just a quick spray, men and women can use hair fibers to get back a full head of hair effortlessly.

While not all of these products are made equal, the best hair fibers are water-resistant and look like real human hair.

Hair Fiber Spray

Hair fiber comes in aerosol sprays that you shake up to charge static electricity and then spray keratin fibers into thinning areas. They also work well as a hairline spray to define the hairline’s ridge. Sprays hair fiber is commonly more effective than powders.

Hair Fiber Powder

The powder form of hair fibers come in a salt shaker style container that you sprinkle along thinning areas to fill in. Though less popular that sprays, powder hair fiber can be a good second option.

Why Use Hair Building Fibers?

Want to camouflage a bald spot forming on your crown? What about filling in spots to get back your juvenile hairline? These are just a couple of reasons why people use these products:

  • Fill in a maturing hairline with fiber spray
  • Cover up wide parts
  • Hide thinning crown
  • Camouflage bald spots

Basically, in any areas where you want your hair to be thicker, you need only do a quick spot spray or sprinkle with a powder applicator. The fibers cling to your natural hair and thicken each area, making your hair fuller.

Pros and Cons

You can easily use hair fibers on your own at home. While you can follow the instructions on these products, there are a number of videos showing you how to make hair look even more natural using these static electric fibers.

How to Use Hair Fibers

Most hair fiber products are powder shakers that may have a tube-like applicator. This allows you to isolate a wide, thinning part or smaller, more specific areas.

Here are the steps to get a natural look with hair building fibers:

1. Clean First

Wash, dry, and style your hair the way you want.

2. Prep Hair Fibers

Shake your hairline spray can to charge up fibers. If using powder, uncap and lightly shake before using.

3. Spray or Sprinkle

Focus the nozzle applicator about 1-2 inches away from the thinning spot. If using powder, position shaker just an inch above the bald spot and sprinkle the fibers.

4. Pat Fibers Gently

To spread fibers and fill in spots, pat each area with your fibers. You may also use a comb or brush to lightly comb in fibers.

Here’s a look at using Toppik hair building fibers with a powder spray applicator.

If you have a hair building fiber with an applicator, use it to pinpoint balding areas, such as a balding hair part. These applicator hair fibers are easily attached to the nozzle, such as with Toppik’s hair building fibers.

Hair fibers work best on dry hair. It’s best if you don’t get hair building fibers wet, as they tend to melt and run. However, some products are waterproof.

FAQ

Do hair fibers cause hair loss?

No, hair building fibers will not cause hair loss, thinning or shedding, as these products do not contain any harsh chemicals. Hair fibers are made of natural keratin and are typically safe for the scalp and hair follicles.

Are hair fibers bad for your hair?

In general, without knowing allergies and sensitivities, applying hair fibers shouldn’t cause any side effects. Some products do include dyes like red 22 and red 33, which can be irritating to some skin types. The top brands have keratin strands and use natural ingredients, such as mineral dyes.

However, there are some reports that if you don’t wash fibers out of your hair or if you have sensitivities to propylene glycol, then you could suffer from acne on your scalp or other irritants.

If you notice dry skin and itchiness after using fibers, shampoo and wash out the fibers. Check the ingredients to see if there are ingredients that cause your skin to break out.

How long do hair fibers last?

This depends on the hair building fiber brand. For example, Toppik claims that hair fibers last for a full 24 hours. Others may only last for a couple of hours, depending on the activity.
The real issue is that hair fibers are susceptible to moisture and may start to wear off if sweat, rain, or other moisture gets in your hair.

For long-lasting use, it’s best to wear hair fibers when you’re headed indoors with air conditioning. Even waterproof or water-resistant hair fibers have issues with washing away and revealing bald spots if exposed to moisture for long periods of time.

Do hair fibers look natural?

When the hair fibers are made from keratin or even a cotton synthetic, hair fibers easily blend in and fill in thinning areas.
Hair fibers may be noticeable if you try to cover larger bald areas. In addition, fibers have to be matched to your hair color. They typically appear darker and don’t hold the light as real hair fibers, however. This is why they should be applied as close to the scalp as possible to avoid dulling your natural hair strands.
