I've been getting my hair done at Sonique for around five years. Prior to finding this place, I had never been completely satisfied with a haircut.
The service and knowledge they offer is what one might expect from a downtown salon (not in Brampton, at least :P). They keep up to date with latest trends and techniques.
I had my hair "ombre'd" and cut last month. The cut (done by Joanne) is fantastic and exactly what I asked for (keep the length, a bit more volume, long layers, etc.), and super easy to maintain. The colour/lightening was subtly done and has gained me lots of compliments. It's clear that the stylists at Sonique are well-trained and capable.
While not the most inexpensive place to get your hair done in Brampton, the cuts I've had usually last for 4-5 months without losing shape/growing out. Depending on the stylist, a wash/cut is around $35-50.
