I think Youtube is fabulous and free for tips and help. I am late 30’s and definitely not looking as I did in my 20’s!
I discovered a couple of things - Queer Eye on Netflix and you tube videos.
Queer eye takes very average people and they change just a few things and makes a fantastic difference.
I then started looking at you tube for make up tips and one thing realised is I needed to overhaul my make up game, as I was still applying it like I had 20’s skin and not adapting for my age!
Also dressing for your age and shape can make a difference.
Also found exercise videos- no need for gym- 20min exercise session in the living room!
Just small things but in the main I would say there must be something you like and remember that everyday!
With your hair go to a different hairdresser and have a proper consultation- can get some highlights through.
Beauty is a lot to do with confidence - although just getting a fab pair of shoes you love can give you more confidence so maybe start there or as others said a make up appointment.
Everyone is beautiful to someone but in the words of Ru Paul “If you can’t love your self, how in the hell are you gonna love someone else”
