A bonnet gathers your hair and keeps it inside a smooth surface all night,\nrather than letting it drag across a pillow every time you turn over. That is\nthe whole idea. It is most useful for curly and coily hair, where friction\ndisturbs the pattern and creates frizz, and for long hair that otherwise ends up\ntangled by morning.
\n\nA lot of bonnets are a polyester shell with a satin lining. This one is\nmulberry silk all the way through, the same fibre as our pillowcases. That\nmatters for heat as much as for feel: a synthetic cap traps warmth against your\nscalp, and silk does not.
\n\nLess friction means less mechanical stress on hair, which is a fair reason to\nwear one and is why people find a style holds longer. We are not going to tell\nyou it stops breakage or makes hair grow. Nothing worn on the outside of your\nhead makes hair grow, and breakage has more causes than a pillow.
\n\nOne size, with an elasticated band firm enough to stay on and loose enough\nnot to mark your hairline. It suits most adults and a decent volume of hair. If\nyour hair is very short or very fine there is less for it to hold onto and it\ncan work loose overnight, in which case a\nsilk pillowcase does a similar job with\nnothing on your head. It is sized for adults, and we do not recommend an adult\nbonnet on a small child.
\n\nCold water, gentle cycle, mild detergent, no bleach, and air dry if you can.\nHeat is what kills the elastic, and the band will give out long before the silk\ndoes. If you use leave-in products, wash it more often than you would a\npillowcase, because everything you put in your hair ends up inside it.
