It’s not uncommon for all of us to try and save money! It’s normal and in fact a good thing, but there is a time and place for everything.
YouTube and the internet is an incredible source of information and we can learn some great skills if we want but there are some things that are simply not DIY friendly. For a lot of people around the world left with no options a DIY haircut wasn’t a choice it simply had to be done snd that’s fine.
It’s not always ( in fact rarely ) going to turn out as you expected because years of training can’t be taught in a 10 minute video but at least it will fix what’s annoying you and give you something to do for a bit!
Now when it comes to color, it’s a lot more complex and easy to end up with a total disaster! Years of training, understanding color and knowing the underlying pigments in your hair along with the pre existing colors you have had it can go sideways fast!
Fixing something like a haircut is fairly simple and you may just need to go shorter than you want but fixing a color is more complicated so you should possibly leave it to the professionals. Who cares if it’s not fresh, doesn’t matter if there is a few white hairs showing. Wait and get it done in a salon when you feel comfortable to step outside!
