Makeup Brush Bristle Guide

The bristle material of a makeup brush is the true foundation of its performance. In custom cosmetic brushes, the choice of bristle fiber determines everything—from texture and surface structure to absorbency and product release. These differences directly influence how smoothly makeup applies, how evenly it blends, and how flawless the final finish appears.

More about

Synthetic fibers are used for makeup brush bristles:

Modern synthetic fibers are widely used in custom cosmetic brushes because of their smooth, scale-free surface that prevents product absorption. This allows liquid and cream formulas—such as foundations, concealers, and tints—to spread evenly without streaks or waste. Synthetic bristles are exceptionally soft, durable, easy to clean, and fully vegan, making them the core of today’s advanced brush technology. With ongoing innovations in materials science, they offer consistent, high-performance results across a wide range of custom cosmetic brushes.

Common Types:

🌟 PBT Fiber (Polybutylene Terephthalate): This is the mainstream material for high-quality synthetic bristles today. It is exceptionally durable, resistant to chemical corrosion (withstands cosmetics and cleaning agents), and easily molded into various shapes and thicknesses.
🌟 “Taklon” (a type of nylon): Once synonymous with high-quality synthetic bristles, specifically referring to an exceptionally smooth and soft nylon fiber. Today, “Taklon” has become a generic term, often denoting high-quality PBT or nylon fibers.
🌟 Performance/Bionic Fibers: This represents the forefront of material innovation. Leading manufacturers (such as Mecobrush) employ patented micro-processing techniques on PBT fibers:
🌹Textured/Bionic Scales: Physically or chemically creating microscopic textures resembling animal fur on smooth fiber surfaces. This enhances powder pickup while retaining synthetic hair's low-maintenance advantages.
🌹Shaped Cross-sections: Features like star-shaped or triangular cross-sections increase gaps between fibers, enhancing fluffiness and powder pickup capacity.
🌹Antibacterial Treatment: Infuses fibers with antimicrobial agents (e.g., silver ions) for enhanced hygiene, particularly suited for acne-prone skin. (Antibacterial Makeup Brushes)

Performance and Application Areas:

🌟 Performance Core: Smooth surface, no hair scales (or controlled texture), non-absorbent to water/oil.
🌟 Application Areas (Liquid/Cream):
🌹Foundation brushes, concealer brushes, lip brushes: This is where synthetic hair truly shines. By not absorbing product, it delivers liquid foundations, concealers, and other wet formulas fully onto the skin without waste. Their smooth surface enables even, streak-free application and buffing for a flawless finish.
🌟 Application Areas (Powder):
🌹Highlighter brushes, blush brushes (for color payoff): Smooth fibers pick up the right amount of powder for precise, highly pigmented application.
High-Performance Bionic Hair (for blending): Specially treated bionic fibers now excel at blending powder products, achieving results increasingly comparable to high-quality animal hair.

Natural Bristle Materials Commonly Selected by Cosmetic Brush Manufacturers

Natural animal hair is highly valued in luxury brushes for its exceptional softness and natural cuticle structure, which improve powder pickup and smooth, even release. Its ability to create soft gradients and seamless blending makes it a top choice for brands developing custom cosmetic brushes, especially for powder-based applications.

Custom makeup brushes made with goat hair:

Goat hair is the most versatile and widely used “mainstay” material in natural bristle brushes. A professional cosmetic brush manufacturer values goat hair for its balance of softness, durability, and superior powder performance, making it ideal for premium makeup brush production.

🌟 Grading (Key): Not all goat hair is created equal. A skilled cosmetic brush manufacturer classifies goat hair based on softness, elasticity, and the integrity of the natural tips. The main grades include:

Saikoho: The highest grade, sourced from the goat’s neck and chin. Exceptionally soft, fine, and velvety with perfectly intact tips. Commonly used by top cosmetic brush manufacturers for luxury powder and blush brushes.
Medium Fine Tip (Zukohoko): Slightly below Saikoho in quality but still offering excellent softness and elasticity. Ideal for high-end blending brushes and face brushes.
Coarse Fine Tip / Medium Coarse Tip (Jukoho): Features stronger elasticity and slightly less softness but provides excellent powder pickup. Often selected for eyeshadow brushes, contour brushes, and tools that require more resilience.

🌟 Applications: Loose powder brushes, blush brushes, contour brushes, and eyeshadow blending brushes—all categories where a reputable cosmetic brush manufacturer leverages goat hair for optimal performance and user experience.

Custom makeup brushes made with kolinsky sable:

Known for its exceptional elasticity and refined tapered precision, this bristle type is highly valued by any professional cosmetic brush manufacturer aiming to achieve superior control and accuracy.

🌟 Performance:
The bristle tips naturally form a sharp, needle-like point and offer excellent rebound, maintaining shape even with repeated pressure. This resilience makes it a preferred choice for manufacturers specializing in high-precision makeup tools.

🌟 Applications:
Ideal for creating detail-oriented tools such as lip brushes (precise lip lining), eyeliner brushes (ultra-fine lines), and professional concealer brushes designed for targeted spot coverage. A skilled cosmetic brush manufacturer often uses this material when producing brushes that require pinpoint accuracy and stability.

Custom makeup brushes made with horsehair:

This material offers a relatively firm texture with good elasticity, though its softness is considered moderate. Because of its stability and resilience, a skilled cosmetic brush manufacturer often chooses it when designing brushes that require stronger structural support.

🌟 Applications:
Highly cost-effective and versatile. Commonly used in eyebrow brushes, where firmness is essential for shaping and combing brow hairs. It is also frequently blended with goat hair by professional cosmetic brush manufacturers to enhance elasticity and improve powder pickup in various eyeshadow brushes.

Custom makeup brushes made with squirrel hair:

Often regarded as the epitome of luxury, this category typically refers to grey squirrel or blue squirrel hair, celebrated for its unmatched delicacy and refinement.

🌟 Performance:
Exceptionally soft with an airy, feather-light touch. While it lacks elasticity, its densely layered cuticles offer superb powder pickup and an ultra-gentle powder release, making it ideal for creating seamless, whisper-soft finishes.

🌟 Applications:
Best suited for techniques that require light, sheer, and diffused application. Frequently used in highlighter brushes (achieving a natural, “dewy glow” instead of a harsh metallic shine), setting brushes, and blush brushes—especially for highly pigmented formulas prone to clumping.
Not recommended for methods involving pressing, tapping, or “poking,” as its delicate fibers are designed for soft sweeping motions.

How to Choose Custom Makeup Brush Bristles: Synthetic Fibers vs. Natural Fibers

🌟 If your brand focuses on vegan or cruelty-free products, opt for high-end synthetic fibers.

🌟 If your brand targets high-end makeup professionals, natural hair like goat or squirrel hair may deliver superior performance.

🌟 For travel or everyday brushes, synthetic fibers are more durable and easier to clean.

🌟 For studio or professional-grade use, natural fibers offer refined texture and effects.

How to choose the hardness of the bristles?

Choosing the right bristle hardness is essential in designing high-performance makeup brushes. The stiffness, flexibility, and resilience of the fibers directly determine how the brush picks up product, blends, and performs. At Meco Brush, we match each bristle hardness level to its ideal application using professional-grade fiber engineering.
