What Are Hair Fibers

Hair fibers act as a hair concealing product, giving your hair a thicker, fuller, and natural look. The fibers are made of hair-like components or keratin proteins of real hair. They are tiny particles that cling to your real hair from the shafts, making your bald patches appear full. They come in the form of powder or spray for applying on your head or beard. These hair concealers match the color of your original hair, giving your thinning patches a good volume.

But how do you know which product delivers the best hair fibers for your hair? Here are the 11 best hair fibers, chosen for all types of hair concealing needs.

Each hair building fiber has its own benefits. It might be confusing to pick the best hair fibers to conceal hair thinning and loss. In this buying guide, we have tried to clear all doubts that you might have about hair fibers.

Buying Guide

Choosing the best hair fibers is not as confusing if you know exactly what you are looking for. Here are a few intricate details to remember:

  • Color: The color of the fiber must match your hair. A black fiber might look good on black-brown hair, but the same hue might make a world of difference when used on other hair colors. Also, the color matters while covering graying or colored roots. All hair building fibers come in multiple colors.
  • Application: Not all hair fibers are easy to apply. While some take barely 30 seconds to settle in, others have a whole process of applying, dabbing, and spraying. Either way, you can select the one that best suits your needs. For example, for models who go for shoots, a quick applicator is important.
  • Ingredients: Any harmful ingredient will give you temporary results but long-term hair damage. Try to avoid silica, parabens, rayon, or sulfate formulas. Instead, go for 100% natural hair fibers or protein-based keratin fibers. You could also look for something that’s vegan and cruelty-free.
  • Environment: Factors such as heat, humidity, rain, or wind directly affect the hair fibers. Get the product that resists all of that and delivers a concealing look at the same time. If you regularly go to the gym, perspiration-resilient hair fiber is essential.
  • Skin-friendly: It is not possible to use any product on a sensitive scalp. Irritation, scalp rashes, or burning sensation is often observed on those with sensitive skin. You can choose natural, hypoallergenic hair fiber for that. Make sure to test on a small patch of your skin for a day before applying it to the entire head.

How To Use Hair Fibers In The Right Way

Hair fibers come in different types of bottles, changing the way they are used. The three basic types are liquid, spray, and powder. The right way is to follow the instructions on the manual according to your hair type. Here are a few common steps you can follow:

Step 1: Spot the thinning and bald spots on your scalp or beard.
Step 2: Apply the hair fibers in the correct amount, good enough for it to adhere to your existing hair. Wait for a few seconds and dab them to spread evenly across the area. You can rely on the applicator to do the job well. If you use a hair thickening fiber spray, the application will not be messy.
Step 3: Keep a cloth on your forehead, perfectly in sync with the shape of your original hairline. Then sprinkle the hair fibers on the crown and temple accordingly. Let the color settle with your natural hair. The cloth helps prevent skin-staining.
Step 4: Use a hair spray that holds the hair fibers, making them stay longer, especially on the crown.
