It's specific to one area of the larger "hair care" industry, and commercial folks tend to prefer a more umbrella term, "HairStylists.com", "HairTreatments.com", and often their own branded non-keyword name.
Ideally it would be a local stylist shop, or an online hair treatment and care info/blog site, but neither would likely pay much for the domain name.
It is directly relevant words, catchy, and people will likely know what it means, and so is very brandable and could easily be used as a commercial website.
You are going to likely sit on this one for some time waiting for the
right end user with a good budget, so I would reach out to already established high end stylists and treatment websites - those coming up from searching Google for "dry ends" who have obviously targeted those keywords. See if they want it to use to redirect to their current site or a page.
Although, these
generally are not worth a lot unless extremely premium keywords and/or high traffic. Worth trying though - email the right company and person and they could be one who likes having a collection of relevant domain names.
I certainly value it at mid 3 figures as a potential for a new brand or redirect, with potential to sell for more, it's just not
likely to be a fast selling one as the buyer potential is low.
Good luck
