If you are able to try on a piece in a wig shop before you commit to buy then you can tell how well it fits, how comfortable it is to wear, if the colour suits you and also the coverage and blend with your bio hair (if you are trying a topper). You will also benefit from fitting advice from a trained professional.
At the time of writing, this is unlikely to be possible in the UK due to COVID-19 restrictions. Regardless of lockdown restrictions, many of us simply do not live near to a wig shop and are having to order blind from online retailers. I have been buying toppers and wigs since 2018 and I have only been to a wig shop once – most of my pieces have been online purchases. I have made a few mistakes along the way, but I can safely say that the most important thing you can do before making that online purchase is to measure your head.
I made this education video with Francesca from Peluka Salon, which offers advice on how to measure your head for a topper.
How to choose a topper base size
These come in different base sizes depending on the amount of coverage you need and the extent of your hair loss. These start from the smaller parting pieces (around 2.5×2.5in), which are good for minimal loss around your parting and for tying up hair in a pony tail. These can add a bit of volume for women with fine hair, but won’t give a huge amount of coverage around the sides or back of the head.
I tend to wear average size toppers (sometimes called mid/progressive), which are anything from 5x5in or 5x6in to 7x7in. These tend to give good coverage of the top of the head/crown area and some coverage on the sides and back. If you have advanced or more severe hair loss, but don’t want to wear a full wig, you can get much larger toppers that are 9x9in and 10x10in. Larger toppers can also be useful if your bio hair is shorter than the topper hair and you want to cover it up, rather than blend the two together.
