Cotton are known to absorb the oils from your hair and skin, which can leave them dry, brittle and prone to breakage. The good news is all these problems are easily addressed by switching to a silk or satin fabric. 
The satin / silk inner bonnet will help maintain the natural oils in your hair and allow for less friction between your hair and other surfaces such as a cotton inner.
It took us some time to create a perfect inner bonnet and finally we have designed a comfortable,adjustable (fits almost all head sizes) inner bonnet with satin linning.
