About Isabella

Isabella Sementilli is a hairstylist at Mare Salon in West Hollywood, where she focuses on cuts and styling. She was born in Canada, grew up in California, and describes her work as lived-in, chic haircuts that pair timeless styles with a California "undone" look. She also takes freelance styling work. Her website lists two Byrdie interviews, one on 90s heartthrob cuts and one on men's hair. On RŌZ Education she keeps her advice simple: wash when your hair is dirty, keep your product routine light, and judge hair health by how it looks after a natural air-dry.

In Isabella's words

Thick or curly hair tends to be naturally dryer, so adding in a thicker conditioner, even a leave-in conditioner to nourish the curls or thickness for longer during the day.

I usually recommend sleeping with a silk pillowcase or hair up in a loose bun or ponytail with a silk scrunchie.

I reach for mousse when my client wants a voluminous blowdry or wants to wear their natural wave! Mousse enhances the natural wave or curl pattern without the crunch feeling.

From Hair Mousse: The Complete Guide

I always tell my clients to wash their hair when it’s dirty. There’s no right or wrong answer, as long as your shampoo is gentle and met with a hydrating finish, wash when you want!

From How Often Should You Wash Your Hair? Is Every Day Too Much?

Healthy hair is when the client’s natural air-dry looks good with minimal product. My simplest advice is don't fix what isn't broken, keep the hair product routine light and simple.
