Less is more

What kind of inspirational photos should I use as reference?

There are a lot of resources on social media, but you can easily feel overwhelmed. I highly recommend to look at photos of woman who have similar hair features such as similar hair color, texture, density and length. For example, if you have dark colored hair, it is not suggested to look at photos with blonde hair. it is easy to be attracted to a certain photos, but we need to have hair that closely matches yours in order to give a realistic expectation of the final result.

Should I wash my hair a night before ?

Yes. If the hair is too oily it can be very hard to manage. Instead, arrive with clean, dry hair so that your stylist can prep it with proper products.
