Struggling to find the right hair products? It might be because you’re unsure of your hair type.
Without knowing your specific type, it’s easy to fall into hair care routines that leave you with frizz, dryness, or weighed-down strands.
Understanding your hair type—from straight to coily, and the finer distinctions of density and porosity—can help you choose products tailored to your unique texture. Discover the best approach to caring for your hair type
Why Hair Types Matter
“Hair type isn’t just about appearance; it’s about your hair’s health,” says hair texture expert Tina Pearson. “Genetics, age, menopause, and hormones all impact texture. For example, if thinning or baldness runs in your family, it’s likely you’ll experience it, too. Don’t worry—just be aware of how these factors affect your hair, as it’ll help guide your styling choices.”
Different Hair Types: From Porosity to Structure
Type 1A Hair
“Type 1A hair is fine, straight, thin, and soft, with a natural shine,” says dermatologist Valerie Callender, MD. “Avoid heavy oils, which weigh it down and make it look dull. Dry shampoo and scalp treatments help remove oils between washes.”
Type 2A Hair
“Type 2A is loose and wavy, forming an ‘S’ shape,” explains Dr. Callender. “Lightweight products like mousse and gel work well to enhance waves without weighing them down.”
Type 2B Hair
“Type 2B hair has ‘S-waves’ that start at the roots and tends to get flat and frizzy,” says hairstylist Chuck Amos. “Avoid heavy styling products and use moisturizing in-shower products like conditioning shampoo and mask.”
Type 2C Hair
Amos describes 2C hair as a loose Brazilian wave. “Use lightweight serums, moisturizing mousse, and light creams for styling. Avoid heavy products like gels or creams, which can make hair sticky and clump together.”
Type 3A Hair
“Type 3A hair has thick, shiny curls but can be frizzy,” says Dr. Callender. “A sulfate-free, moisturizing shampoo and conditioner add daily hydration. Use creams and jellies for control and definition.”
To determine porosity, Abergel suggests dropping a strand into water. “If it floats, you have low porosity. If it sinks to the middle, it’s medium; if it sinks to the bottom, it’s high porosity. Medium-to-high porosity hair benefits from hydrating oils for shine.”
Type 3B Hair
“This thick, coarse texture has curls that vary in shape,” explains Sierra Britt of Pattern Haircare. “Dryness is common, so moisture helps maintain definition and shine.”
Type 3C Hair
“3C curls are pencil-tight and need lots of moisture,” says Amos. “Use buttercreams, serums, scalp oils, and curl creams. Avoid gels and products with drying agents.”
Type 4A Hair
“4A hair is tightly curled or kinky with thick, defined curls,” says Dr. Callender. “It can be dry, so use a shampoo and conditioner designed for curly hair.”
Type 4B Hair
“This type has Z-pattern coils and needs plenty of moisture,” says Britt. “Protective styles help keep it moisturized, support ends, and retain length.”
Type 4C Hair
“4C hair has the tightest curl and is most prone to breakage,” explains Amos. “It typically has little curl definition and a lot of shrinkage. Use hydrating creams, serums, and light curl definers for best results.”
“The more textured your hair, the more moisture it needs,” adds Rosebrook. “Moisture—oils, lipids, sebum—coats, seals, and protects hair.”
Why Hair Types Matter: How Knowing Your Type Can Help
Understanding your hair type isn’t just about defining curls or waves—it’s a guide to treating your hair the right way. Each type has distinct care needs:
- Density: Refers to how much hair you have, affecting how thick or thin it feels. Products need to match both your type and density.
- Porosity: Determines how well your hair absorbs moisture. High-porosity hair needs extra hydration, while low-porosity hair benefits from lightweight, moisture-locking products.
- Curl Pattern: Helps with product selection, as tightly coiled hair needs more moisture and gentle handling than straight hair.
Tips for Healthy Hair Based on Type
- Straight Hair (Type 1): Use lightweight, oil-free products to avoid flatness and add volume.
- Wavy Hair (Type 2): Opt for mousse or gels that enhance natural waves without weighing them down.
- Curly Hair (Type 3): Moisturize regularly, and use curl-defining creams or jellies to keep curls looking bouncy.
- Coily Hair (Type 4): Prioritize moisture, and consider protective styles to retain length and prevent breakage.

FAQs Asked Questions About Hair Types
1. What are the 4 main types of human hair?
The four main hair types are straight (Type 1), wavy (Type 2), curly (Type 3), and coily (Type 4). These categories are based on how each hair strand naturally grows, from straight lines to complex curls.
2. How do I figure out my hair type?
The easiest way is to examine your hair when it’s wet. After washing, let your hair dry without adding any products. Then, observe the pattern it forms: if it stays straight, you’re likely Type 1; if it creates waves, you’re Type 2; if it forms curls, you’re Type 3; and if you see tight curls or coils, you’re Type 4.
3. Am I 2B or 2C hair?
If your hair has loose waves with minimal frizz and a slight “S” shape, it’s likely 2A. 2B hair has more prominent waves with a bit of frizz, often lying closer to the scalp. Meanwhile, 2C hair has thicker, defined waves and more frizz. It may start forming loose curls.
4. What is the rarest hair type?
Type 1A is considered the rarest, as it’s extremely straight and lacks any natural body or wave. This hair type is typically very fine and silky.
5. What is the most difficult hair type?
Many consider Type 4C hair the most challenging because it has tight coils, little to no curl definition, and is prone to shrinkage and dryness. It requires consistent moisture and gentle handling to maintain its health.
6. What does 2C hair look like?
Type 2C hair features thick, well-defined waves that start near the roots. This hair type often has some frizz, especially in humid environments, and can easily transition into curls with the right products.
7. What is 4C hair type?
4C hair is the most tightly coiled hair type. It usually lacks a defined curl pattern, with curls forming a “Z” shape. This type is prone to shrinkage and dryness, so regular moisturizing is essential.
8. What are the types of 100% human hair?
In hair extensions, 100% human hair comes in various textures such as straight, body wave, deep wave, and curly. Each has a unique look and maintenance requirement.
9. What does 4B hair look like?
Type 4B hair has a tighter curl pattern than 4A and bends in a zigzag “Z” shape rather than a true coil. This type is dense, voluminous, and requires extra moisture to avoid breakage.
10. What are all girls’ hair types?
Girls’ hair types are categorized the same way: straight (1A-C), wavy (2A-C), curly (3A-C), and coily (4A-C). Each type has unique characteristics and care needs.
11. What are the top 5 hair types?
While each hair type is unique, the most common types worldwide include 1B (straight with volume), 2A (loose waves), 3B (tight curls), 4A (coily with defined curls), and 4C (tight, coiled texture).
