EXCELLENT Based on 319 reviews Posted on Google Steven FoldesTrustindex verifies that the original source of the review is Google. My first haircut at Slope Suds and I’m a happy camper. Thank you!Posted on Google amy telseyTrustindex verifies that the original source of the review is Google. Amanda has given me great precise haircuts in the past. I came in for a bang trim to add some more shape around my face. She has only cut my hair about a half dozen times, so I know it takes time to see things the same way and communicate. She added a lot of texture to my hair and I was unsure that that was what would give me the hairstyle she had done in the past. She seemed to become pretty upset with me. I would like to have her cut my hair again in the future, but am concerned I made her angry with me.Posted on Google Breighton “Donie” MageeTrustindex verifies that the original source of the review is Google. Alessandra gave me the best shampoo/head massage I’ve ever had. Very happy with my haircut and blow out!Posted on Google George OwTrustindex verifies that the original source of the review is Google.

I love my haircut. It makes all the difference between looking like an old hag or a hot boss woman.Posted on Google Abigail KersonTrustindex verifies that the original source of the review is Google. Nallely has been doing my cuts and color for a few years now, and I had the pleasure of having her do my hair for my engagement party a few days ago! She did a wonderful job and was so helpful when I couldn’t decide what I wanted! It stayed gorgeous the whole day!Posted on Google Hope M.

A double process color is a two-step coloring technique that first lightens the hair and then applies a toner or desired color to achieve an even, vibrant, and customized result.
2. Is a consultation required before a double process color?
Yes. A consultation allows our color specialists to evaluate your hair’s condition, discuss your goals, and determine if a double process is the best option for achieving your desired color safely.

The appointment time varies depending on your starting color, hair length, and desired result. Most double process services take 3 to 6 hours to complete.
