Why is colour correcting shampoo a must have? I've not heard this mentioned before.
Can you recommend some good mild shampoos, conditioners, and leave in conditioners to try?
I'm looking at the Walker 3-mil / lace front thin tape and it comes in strips of A, B, CC and D contour shapes. How do you get these pre-defined contour strips to fit exactly the front edge/ hairline of a custom system?
