An old friend of mine created his own YouTube channel dedicated to roller sets and extreme shampooing. So far, he has full-length videos on there. You can find that channel at https://www.youtube.com/channel/UCCNKLZRvR4nggKJKBhQeAFg

The Mistress stylist in one of the videos has her own YouTube channel (and domme hair salon) at https://www.youtube.com/channel/UCZwOawC_GYhXvY7iC9AZFqQ Warning - videos may be too risque for work.
