After the work is done, we off the clients knowledge on how to maintain their hair extensions so that they feel comfortable managing them once they leave our hair studio.

I average about 60 new clients per year with a retention rate of 95%. The majority of my clients will come back for every month to have their hair managed and touched up.

I first started the hair business by importing and selling my very own Virgin Hair Extension product line in 2011.

The project that I am most proud of is a cancer survivor who came to me to have hair extension done after loosing her hair during chemo.

Before a customer hires a professional stylist, they should ask what is best for THIER hair. Not all extension methods are appropriate for all hair types. if a professional is able to make recommendations for you specifically, they are hirable.
