I have been going to Tiffany for years, and she is amazing. Having a natural look is very important to me. She always takes time and care to dye small, individual sections different colors to make me look like a completely natural blonde. I have also had great luck with her haircuts. I have very thin hair. She does a great job making it look like it has some volume. I have always walked away happy with the work she's done.
I saw a previous comment by a male customer that did not have the same positive experience with Tiffany as I have had. I would suggest making an appointment with Allen next time. He worked across from Tiffany for years. From what I saw of his clients they were predominantly male, and he always did a fantastic job.
