Buying Guide

When it comes to finding the best hair thickener, it can be a challenge to find the perfect product for you. In this guide, we will discuss the most important factors to consider before purchasing a hair thickener. First, understand the four types of hair thickening products: polyester, keratin, cotton, and synthetic. Polyester fibers are usually made of a fine synthetic material that closely resembles real hair. Keratin fibers are made up of natural proteins that are similar to the ones found in human hair, giving a more natural, shinier look than polyester fibers. Cotton fibers are made from natural cotton fibers and are best for those with sensitive scalps. Synthetic fibers are made from a combination of polyester and nylon fibers. These fibers are more affordable than natural fibers, but offer a less natural look. Once you have chosen the type of hair thickener, select a product that best matches your hair color and texture for a seamlessly natural look. Hair thickening products feature different levels of coverage. Choose one that provides the level of coverage you desire. Since this is a personal investment, consider whether the benefits of the product match up to the price. Last but not least, check the ingredients of the product to avoid scalp irritation. If you have a sensitive scalp, it may be best to use a hair thickener that is 100% plant based. Taking these points into consideration will lead you to the best hair thickening product for your needs.
