Tammy KILLED it! 👩‍🦳 This was my first time going to her, and it will not be my last! She removed my outgrown wefts, brightened up my roots with full highlights, matched color to my extensions, reinstalled sew-in extensions, and gave me a trim to shape and a style! I couldn’t be happier! She was also really…
