Hair is thinning and greying at 23

I’m a 23 y/o female and I’ve noticed that my hair looks noticeably thin on the top, especially near the front. I also get quite a few random strands of grey hair.

My hair is wavy/curly and here are the products I typically use…

- head and shoulders tea tree shampoo

- garnier hair filler conditioner

- ouai scalp serum

- ouai leave in conditioner

- bumble and bumble curl cream

- pattern mousse

- not your mothers gel

I also sleep with a bonnet and satin pillow case.

Not sure if this would affect it, but I’m on lexapro.

Does anyone have any tips for products/supplements/foods that could help me?
