LIKELY THE FIRST HOOD TO STAY ON YOUR HEAD: The elastic drawstrings allow you to gently tighten your sleep bonnet and keep it in place. While we can't give you a 100% guarantee that the bonnet will stay on your head all night long (we all sleep a little differently after all), we can promise it will keep your hair shiny and moisturized. EXTRA LARGE BUT ADJUSTABLE: Big enough for long thick hair and yet adjustable for all other lengths and types of hair. Soft and elastic drawstring that fits all adult head sizes and any type, length, and amount of hair. SPA-LIKE TREATMENT FOR YOUR HAIR: A daily and simple must-have for your beauty. Our silk caps lock in moisture, giving your hair a spa-like treatment every night. They keep your hair shiny and moisturized with less split ends, less hair loss, and less tangles. They also keep your curls defined and your long hair smooth, manageable, and easy to brush. Silk sleep bonnets are a perfect choice for natural hair, long hair, braids, weaves, curly hair, updos, rollers, hair clips, split ends, and so on. IDEAL GIFT CHOICE: The cap is a fantastic gift for countless occasions. Mother's Day, your bestie's or girlfriend's birthday, a fun Christmas gift, a Valentine's Day treat, a gift for your sister or wife, and a perfect bridesmaid gift that gives you and your girls a great photo option.
