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.

Alan has given me the best haircut and color I’ve ever had. He is truly an expert at his craft. He also is not pushy and trusts the client.

FAQS
FAQS
1. What is semi-permanent hair color?
Semi-permanent hair color is a gentle color service that enhances your hair without permanently changing its natural color. It gradually fades over several weeks with regular shampooing.
2. How long does semi-permanent hair color last?
Most semi-permanent hair colors last 4 to 8 weeks, depending on your hair type, the shade selected, and how often you wash your hair.
3. Will semi-permanent color damage my hair?
Semi-permanent color is generally less damaging than permanent color because it does not require the same level of chemical processing. It is a great option for adding color while helping maintain your hair’s natural condition.
4. Can I add a hair treatment to my semi-permanent color appointment?
Absolutely. We recommend pairing your color service with a deep conditioning, hydration, or bond-repair treatment to keep your hair healthy, smooth, and shiny while extending the vibrancy of your color.
5. Is semi-permanent color good for covering gray hair?
Semi-permanent color can help blend early gray hairs and soften their appearance, but it does not provide full, long-lasting gray coverage like permanent hair color. During your consultation, our stylists can recommend the best option based on your desired results.
