Know your hair type before you buy products

Texture, density and porosity decide what actually works.

Short version: "Dry" or "frizzy" isn't a hair type. Three things decide what works: texture (fine/medium/coarse), density (how much), and porosity (how it takes in moisture). Buy for those, not the marketing.

The three that matter

Texture — the width of a single strand. Fine hair is weighed down by rich creams; coarse hair drinks up oils and butters.
Density — how many strands. Thick hair needs more product and stronger hold.
Porosity — how easily the cuticle absorbs and holds moisture. Low porosity repels product (use lightweight, warmth to help it absorb); high porosity loses it fast (seal with creams and oils).

The quick porosity test

Drop a clean strand in water. Floats = low porosity. Sinks fast = high porosity. Hovers = balanced. Match your products to that and you stop wasting money on the wrong formulas.
