Sonal Sehgal

Sonal Sehgal is a licensed cosmetologist, pharmacist, and certified Cranial Prosthesis Specialist based in Fremont, California — and her story is one of the most compelling in the field.

After spending years in the medical world as a pharmacist, Sonal realized that her love for hair and beauty could be another meaningful way to make a difference in people's lives. That realization became a calling, and that calling became Hair by Sona.

Today, Sonal operates at a rare and powerful intersection: she understands the pharmacological side of medical hair loss — the treatments, the side effects, the clinical realities — and she brings that knowledge into every consultation alongside her cosmetology expertise. The result is a level of informed, holistic care that most specialists simply cannot offer.

What do you enjoy as a Cranial Prosthesis Specialist?

As Sonal continued her education in cosmetology, she discovered the world of cranial prosthetics — and immediately recognized it as the place where her two passions converged.

Her medical background and her love for hair did not just complement each other in this field. They completed each other.

What she enjoys most is the life-changing impact that a well-fitted cranial prosthesis can have for someone experiencing hair loss due to cancer treatment, alopecia, or another health challenge.

Having spent years in a pharmacy watching patients navigate illness and treatment, she already understood the emotional weight of medical journeys. Now, she is privileged to be the person who offers something those journeys often lack: a moment of beauty, restoration, and genuine joy.

How do you want to help your clients?

Sonal's mission extends far beyond creating beautiful hairstyles. It is about restoring confidence, dignity, and hope — one client at a time. Whether through hair color, extensions, hair systems, or medical-grade cranial prosthetics, she wants every person who sits in her chair to feel seen, supported, and empowered.

Her pharmacist background gives her a uniquely practical advantage when it comes to understanding scalp sensitivity, medication interactions, and scalp health during and after treatment — allowing her to recommend solutions with a level of clinical precision her clients truly value.

She also helps clients navigate insurance coverage for cranial prostheses with the same thoroughness she once brought to pharmacy benefit management. Helping people has always been her purpose — and at Hair by Sona, that purpose has found its fullest expression.

What do you love about the community you work and live in?

Sonal loves the extraordinary diversity and richness of the San Francisco Bay Area.

Living and working in Fremont gives her the opportunity to serve a wide range of individuals — from many different cultural backgrounds, life experiences, and health journeys — all of whom are searching for compassionate, personalized hair loss solutions close to home.

She believes deeply that everyone deserves to feel confident and beautiful, regardless of what they are going through.

By combining her background as a pharmacist with her expertise as a licensed cosmetologist and Cranial Prosthesis Specialist, Sonal is committed to making a meaningful difference in the Bay Area community — and beyond. Every client who walks through her door has a story. And she is honored, every single time, to be part of it.
