The content on TikTok is far-reaching. The hashtag #scalp has 777.4 million views, #scalpcare has 268.8 million, and #scalpmassage has 77.6 million.

And the fact that scalp issues can be both physically uncomfortable (think: itchiness and tightness) and physically embarrassing (flakes and hair loss) means that the subject is ripe for TikTok.
