Your welcome I am an aspiring cosmetologist and I LOVE working with HAIR and making cheap hair work and look expensive! I would love to have an assortment of trans clients because I know it would be hard for someone to try on wigs and get them styled or cut when they are starting transitioning or don't pass. Since I'm trans too they wouldn't have to worry about feeling uncomfortable or being outed and put in danger.
I do agree they can be itchy and hot when its warm out where I live it can be up to 110 degrees I am just used to it and the wigs are. The wigs I buy are all what is called "capless" where you can itch your head through the tracks and allows air to circulate. Wearing a stocking cap also prevents itching. Its just something your going to have to get used to. Its the only option for me as I have a very male hairline hair thinning and a big forehead so bangs really feminize my features. I can't afford a hair transplant.I still pass without one but I don't feel very fem or confident without it in public. My hair is getting thicker and growing on spiro though so I'm crossing fingers. My real hair is boob length and I just wear it in a middle part. It is too thin on top to do bangs at the moment

I just stick with the same style because If you wear a different wig everyday people will know lol. Thats why it's nice to get a wig with a bang because you can pin it back curl it wave it straighten it side bang front bang ponytail bun the options are limitless.
Yes they do but a trick around that is to get a wig with a dark root there are also tutorials on youtube on how to add a dark root to a blonde wig. You wouldn't need to fill in your brows because they have a brown tone to them. A suggestion is to have your brows shaped and thinned because you have a beautiful face and that would compliment and feminize it more. I know I have to pluck mine frequently LOL I don't do bushy brows. Not that my wig bangs don't cover them XD.
I wouldn't feel comfortable doing so whenever I go to a black beauty supply I get looks like "you don't belong here" from other customers because I'm white. It's embarrassing for ME to put myself in a situation where I will be seen as trans when I PERSONALLY just want to and do blend in.
I don't know the details of your relationship but if your S/O isn't supportive and is critical now you really need to work that out because she can really hinder your transition. Don't rely on others to make yourself feef confident you have to find it within yourself. That's why I give SUGGESTIONS not ORDERS

. If you want to you can PM me if you have any hair questions I'd be happy to help.
