My satin bonnet is probably the best purchase since my hair journey began. I wish I purchased it earlier, it was about £2 from my local BSS, Julia's - I wear it nightly without fail whether I am on holiday, at a friend's house I never forget to pack it.
At night, I moisturise (I seal in the morning) and tie my hair in a bun with an ouchless band:
(I only do this if I plan to bun the next day, if you want to see how I prepare for a braidout click here, or how I wrap my hair if it's straight click here.)
I wake up, seal and style. Simple :)
