When you hear hair typing system, a classification method used to identify natural hair textures based on curl pattern, porosity, and density. Also known as the Andre Walker system, it’s not just a trend—it’s the first real step to stopping guesswork in your hair routine. Most people wash, condition, and style their hair the same way as someone with completely different needs. That’s why your curls fall flat, your coils get frizzy, or your fine hair looks greasy by noon. The hair typing system breaks hair into clear categories so you know exactly what your strands need.
It’s not just about whether your hair is curly or straight. The system looks at three big things: curl pattern, how your hair naturally forms waves, spirals, or coils from root to tip; hair porosity, how well your hair absorbs and holds moisture; and hair density, how many strands grow per square inch on your scalp. These aren’t just labels—they’re clues. High porosity hair soaks up moisture fast but loses it faster, so it needs heavier oils. Low porosity hair repels water, so it needs lighter products and heat to open the cuticle. Thin density hair gets weighed down easily; thick density hair needs more product to get full coverage.
You’ll find posts here that connect directly to these ideas. One looks at the science behind washing your hair at night versus morning—something that affects different hair types in very different ways. Another breaks down the exact extensions the Kardashians use, which only work because they match their specific curl pattern and density. Even salon job titles matter here—because a good stylist knows your hair type before they touch a single strand. You won’t find fluff here. Just real talk about why your hair behaves the way it does, what products actually work for your type, and how to stop following advice meant for someone else’s scalp.
