Beware I have not tried this myself, this is information I found which I thought would be helpful. I would suggest having a good look at these clips or similar before you give it a go. Starting very gently.
There are various DIY (do it yourself) tips and hints being created. I thought you always cut your fringe flat against your head!
‘This morning’ 3rd April 2020 was – https://www.itv.com/thismorning/hot-topics/how-to-do-a-salon-haircut-at-home
‘This morning’ TV 20/04/2020 had the same hairdresser Michael Douglas also giving tips on how to carefully cut your own hair. https://www.itv.com/thismorning/style-beauty/heres-how-to-cut-your-hair-at-home
Michael said there are lots of tips in Instagram. He cut ones sons head off totally and how to use clippers. How to do a fringe, lift the hair up. To keep the fringe longer at the sides is a softer effect.
If you do not have good scissors he suggested getting some from Amazon for about £20.
I caught a glimpse of this program for the first time 05/05/2020 sounded like good clear advice. I like the hair cutting tips and for the men in your life how to trim a beard!
Later on in the above episode Angela Rippon was saying how important a good hair cut was. She had been lucky enough to go and have her hair cut locally just before the lock down!!
Stay safe and have fun xx!
