Ok, firstly, stop fucking with your hair. You’re being utterly ridiculous.
Secondly, no, it won’t have damaged your baby. Especially if you haven’t actually applied any to the roots. So pack that daft thought in.
Thirdly, you need to find a better stress outlet than dying your hair. A gentle face pack or pregnancy massage would make much more sense.
Fourthly, get a nice sachet of richly intensively moisturising hair masque. Wet your hair but don’t wash it. Slather it on all of your hair from root to tip. Cool your hair, covered in product, on top of your head and wrap the whole lot in cling film (just your head, not your face...) so it forms a skull cap. Then wrap a warmed towel around the whole lot and put up in a turban. Leave that on for as long as you possibly can. Hours if possible. Then rinse and gently comb and leave to air dry. Repeat as necessary.
Fifthly, go for a free consultation at a reputable salon to see what they can cut back and gently restore so you’re happy.
Sixthly, calm the fuck down.
