Need to make more effort.......??? finding it hard :/?

I have recently gave birth to a beautiful baby boy and i no longer feel confident enough about the way i look anymore... my partner has handed me money to buy myself a whole new wardrobe and to get my hair and nails done but i just cant. i dont know why! so anyway id like to find my perfect hairstyle before having it cut and dyed so does anyone know any good website with different hairstyles and hair colours? thankyou xx
