Why synthetic hair so popular compared to animal hair?

Synthetic bristles are becoming increasingly popular in the makeup brush world. Fay has been in makeup brush industry over 20 years, we started the business of animal hair before manufacturing makeup brushes, we are an expert in the industry of brush bristles.

Synthetic bristle is a man-made fiber that mimics the texture and properties of animal hair. The synthetic hair makeup brushes are usually made of materials such as PBT and PET. The degradable and environmentally friendly bristles are made of PLA. Unlike natural hair, synthetic makeup brushes are not obtained from animals and are therefore cruelty-free. This makes them more ethical and vegan, it's a great choice for vegetarians.

Diameter. Some hairs are soft and some are stiff, because the diameters of the hairs are different. The diameter of the hair used for makeup brushes is usually 0.06-0.1mm. The larger the diameter, the harder the hair.

Waviness. There are two types of waviness of synthetic hair, namely straight fiber and curved fiber. Curved fiber is divided into low wave, medium wave and high wave. Straight fiber bristles are generally used for makeup brushes that apply creams or foundations, while curved fiber bristles are generally used for makeup brushes that apply shadow, blush or powder. Low-wave bristles can also be used on round foundation brushes.

Hair tips. The tips of the bristles directly affect the touch feeling. If the synthetic bristle brush stick to the face, it means the tips are not good. It is better for eyeliner brushes and lip brushes to have slightly longer hair tips so that they can draw finer lines.

Mixed hair. Mixed hair can be straight fiber mixed with curved fiber, synthetic hair mixed with animal hair. Some specific brushes use mixed bristles to make makeup more effective.

Additionally, synthetic bristles offer many advantages over animal hair makeup brushes.
First, they are less likely to fall off and break, which means they are more durable and last longer.
Secondly, they don’t absorb as much product as natural bristle brushes, resulting in less waste of expensive makeup products.
Finally, they are easier to clean and dry faster, making them more hygienic and convenient to use.

All in all, synthetic bristles are a great alternative to natural real hair makeup brushes. They are becoming increasingly popular in the cosmetics world due to their durability, convenience and ethical qualities. So next time you’re looking for a new makeup brush, consider giving synthetic bristles a try!
