I've been doing locs for over 12 years. I interlock and style dreadlocks. I even repair, reattach, and strengthen damaged locs.
$100 for basic interlocking
$50+ for add-on services depending on length and thickness
I can't find all my photos, but what I've attached should give a general idea. And if you send me a photo of what you want your hair to look like, I can let you know if it's doable or not.
PS: I DO NOT wash hair anymore. Please come with clean locs, or I will turn you away. Thanks for understanding.
