Tips for soft hair

I know this shouldn't be on here and it should be posted in a different group but I get more replies on here so ima go ahead and post this , okay when I was pregnant my hair grew and was soft , after having my baby I bleached it . My hair was so dry but  I recently went back to my natural color and my hair is starting to feel a little soft now i'm curious to know does anyone know anything I can put in my hair or any shampoos that help make your hair super soft ? My friend had platinum blonde hair and her hair was baby soft she said she put coconut in her hair every day but what other things are there to do ?
