Free long-hair diagnosis.
Before we touch your hair, we read it. A one-to-one consultation that looks at your scalp, the structure of your lengths and the condition of your ends, so every step after is chosen for your hair, not a generic routine.

What your hair gets.
Read before you cut
We look at what your hair needs before deciding what to do — so nothing is cut or colored by habit.
Scalp to ends
Scalp, mid-lengths and ends are assessed separately, because they rarely need the same care.
A plan you understand
You leave with a clear, written plan: what we suggest, why, and in what order.
No surprises
We discuss timing and price before anything starts. You decide.
How it works.
- 01
Listen
Your history: color, heat, products, breakage, and the length you want to keep.
- 02
Look closely
We check scalp, porosity, elasticity and ends under good light.
- 03
Plan
We propose a personal path — treatments, cut, color — and how often.
- 04
Decide
You choose what to book. There's no obligation.
Frequently asked.
Is the diagnosis really free?
Yes. It's included with every first visit to Wonderlong Aventura.
Do I need to wash my hair before?
No. Come as you are — we need to see your hair in its everyday state.
Can I book only the diagnosis?
Yes. Book it on its own, or together with a treatment or cut on the same day.
How long does it take?
Usually between 20 and 40 minutes, depending on your hair and questions.
