Ok, let’s explore another fantasy. Noting you can search hair color on the various ad sites, are there any DC/Tysons-based  providers with *natural* (not dyed) red or strawberry blonde hair? Bonus points if she also has pale Irish/British Isles/Scandinavian skin.

These "I know you can search, but..." posts always intrigue me. If you are looking for a provider that doesn't advertise (UTR or otherwise) you should say so. However, if she doesn't advertise she probably doesn't see anyone else and doesn't want her information out on a public board (as is the case with my ATF). Otherwise, most of the redheads who advertise usually indicate if they are natural redheads or their ethnicity and the pale skin and freckles are somewhat of a giveaway.  Just wondering what am I missing?

The search function will pick up a binary red or not red, true. But there is no search key for natural color. It also probably misses strawberry blonde, auburn, and other such synonyms. Additionally, many providers blur faces and inked skin to keep anonymous or conceal age, so skin tone can be difficult to distinguish with some ladies. And thanks to all repliers. I genuinely appreciate others’ advice here in the forums.

I think you're asking for a lot when it comes to searching for natural vs dyed. If you search for and find redheads and you see one of interest simply ask her if she's "real" or not.

All I can say is that the Tryst search engine addresses all you points except for what is intentionally hidden or self reported (and here I state the obvious). A targeted search within 60 miles of DC yielded 50 potential candidates with 5 or 6 indicating "natural" and at least one standout from Scotland.

Thanks everyone. Appreciate the advice.

You're right that you're not going to get that type of granular filtering here (or probably any other site) but that filter does get you a collection of reviews and reviewers. Read the reviews, some might mention what you're interested in. PM the reviewers to see if any can answer your questions.
