I wear a wig and it's been a life-changer for me. I've always had fine thin hair but a medical condition accelerated the thinning to the point where I hated going out, especially if it was windy or raining.
The wig I wear is a synthetic one (Amy) from the Ellen Wille range, and is my second one since mid-2018. They cost around £200 (exc VAT which I don't pay as I asked my GP to sign a form to say it was required for medical reasons.)
I bought mine from a lovely local lady who provides wigs for the public and for hospital patients. She was very understanding and talked me through the differences between synthetic and real hair (and now there is also a blend of both types). She ordered three for me to try and, at this second visit, she fitted the one I chose and it was cut and styled (thinned out) there and then by a professional hairdresser.
Synthetic wigs are said not to last as long as real hair wigs - about six months - but I get nine months' wear from mine. You need to wash it every 7-10 days using specially-formulated shampoo in lukewarm water then swish it around before rinsing and putting them on a wig stand to dry. In the morning, just pop it on your head - and that's it.
Synthetic wigs need very little attention once you've had them styled to suit.
My hair always looks great - as I've always hoped it would be - and very natural. No-one believes it's a wig. I chose the colour Dark Sand Rooted (so it's low-lighted rather than a solid colour). I wear my wig all day and absolutely love it! It has honestly given me a new lease of life!!
