Your hair has a structure, and once you understand it, everything gets easier. The Basic Analysis puts your actual strands under a microscope to reveal the three things that decide which products will work for you: your porosity, strand width, and elasticity. You'll walk away knowing what your hair needs and how to make smarter choices on your own.

What's included:

• Your porosity, strand width, and elasticity results

• 10–15 high-resolution microscope images of your hair (root, midshaft, and tip)

• A buildup, UV damage, and breakage assessment

• General guidance on what your hair needs 

Want your current products reviewed or specific products picked out for you? That's what the Premium and Complete Analyses are for.
