Buying Guide

Dealing with hair loss or thinning hair can be devastating for many people. No matter your age or hair type, it can feel like losing a part of yourself when it starts to thin. However, if you want to reverse course, you have options. One way to deal with thinning hair is to use hair fibers to make your hair fuller, thicker and healthier.

What Are Hair Fibers?

Made from keratin protein, hair fibers are tiny strands that you can apply to your existing hair. They cover bald spots or bald patches as well as thinning hair, and look like natural hair. Hair fibers stay on to your head by clinging to the existing hair on your head. They also mimic the density, movement and appearance of natural hair.

One of the greatest advantages of using hair fibers is that they are easy to apply. They don’t require a lot of prep or time out of your day. The fibers come in a bottle with a sifter cap on top, similar to a salt or pepper shaker. To apply the hair fibers, you just have to shake the bottle cap down on your head in the areas where you want to apply the hair fibers.

Hair fibers come in a range of natural hair colors, so you can find one that matches your look. Even if it doesn’t match your hair color exactly, the fibers tend to blend in fairly well with any natural hair shade. Most hair fibers are also resistant to wind, so they won’t blow off your hair once applied. You can go for a run or potentially even ride in a convertible without worrying about the hair fibers falling off. Some can even be blow-dried.

What to Look For

  • The most important thing to remember when you’re applying hair fibers for thinning hair is to make sure your hair is fully dry beforehand. If your hair is wet, the hair fibers will end up looking lumpy and clumpy. Dry hair helps them spread out evenly and look more natural.
  • If you can’t find the exact color of hair fibers to match your hair, you can mix two colors together to find the perfect look. Always apply the dark color first as a base and then top it with the lighter color to add highlighting.
  • How do hair fibers attach themselves to your hair? It has to do with static. If you don’t have much existing hair or have a very short hair cut, it might be hard for the hair fibers to attach to your hair. However, don’t fret. Even those who look like they have bald spots often have very tiny hairs in the spot to which the hair fibers can cling.
  • When applying hair fibers, always start with a small amount first. If you add too much initially, it may look odd and unnatural. Instead, apply a light layer first and pat it in lightly with your fingers. If you feel like you need more, you can always add in another layer of fibers on top of the initial layer.
  • You can brush your hair when you have hair fibers in, but you have be gentle. Be sure to use a brush that won’t tug on your hair or the hair fibers, and be sure to not apply too much pressure when brushing your hair.

Hair Fiber Maintenance

Like most hair products, hair fibers  will wash out with water. For example, if you’re out in a downpour or going swimming in the pool, your hair fibers will likely come off when they get wet. Some people use a hair-fiber holding spray, but this product can also wash off with water. If you’re planning on using hair fibers, be sure to consider what activities you’re going to be doing that day and whether it will be compatible with your hair product. If not, you may want to skip applying them on certain days.
