An itching weave has causes, and Maiysha Johnson names them: the chemicals and the glue used to make most extensions, and what those do to a scalp over time. She is a hairdresser writing for women who wear extensions, and the difference between that and general beauty content shows in every post.
The care advice is specific. Why hair goes brittle and what to do about it. What tension alopecia is and what habit produces it. How a set of extensions stops shedding and tangling. Which conditioner suits dry hair that has been chemically treated.
She also sells into a company built around selling human hair through a network, and writes for consultants trying to move that business online rather than only through a salon chair.
There are beauty and weight posts at the edges, and they are the ordinary sort.
If you wear extensions or fit them, this is a working stylist writing about your actual problem.
