"I love it! I purchased the hot pink hairbrella and I wore it to swimming lessons with boho knotless braids underneath. I was fully submerged in the water, swimming and floating and not a single damp area of my hair after! I will be buying a new color cap every month. No more pulling my skin back and hairline back in the sake of a swim cap that won’t guarantee my hair will stay dry. Thank you! I will be recommending this to all my friends and family❤️"
"I love the hairbrella swim cap. I have been struggling with my hair getting wet during my swim class and when I recently used the cap for the first time only my ends got a little wet and I think it’s because I didn’t pull my hair up enough in the back. I am planning on sharing your site with others."
"I do get some water seepage at the hairline all around when I go under water, but the majority of my hair in the ponytail stays dry. Big improvement from other caps. I tighten the straps until it starts riding up."
"I freaking love this swim cap! I have a special needs daughter who has aquatic therapy every week. Hairbella has saved me from having to wash her hair every single week. She has had two swim sessions so far & her hair hasn't gotten wet at all!"
"I love this swim cap, as I'm in the pool multiple times a week and my heavy, curly hair was taking a beating. I love the satin lining and the fact that I can adjust the band size so that it doesn't give me a headache (like most swim caps do). The satin lining adds to the comfort."
"The product works wonderfully and the customer service was great when my order was shipped incomplete. They immediately shipped the second swim cap asap. I was in Mexico with fresh braids and it kept my hair completely dry! Thanks!"
"In the beginning there was some issues with my swim cap, but customer service was awesome. We eventually decided to try a smaller size swim cap. It works perfectly. Excellent customer service."
"Absolutely love this product. Fit my baby’s head perfectly. Will be purchasing additional products in the near future!"
"Love this swimming cap! For the first time, I feel confident swimming, knowing my hair won't get wet thank you!"
"This is an amazing product it protects her hair and my daughter doesn’t mind wearing it summer is gna be great in the water…. ."
A labor of love! I'm thrilled to introduce our new swim cap. We have had some exciting releases, but this is the one I've looked forward to the most.
I've been working on it for two years and refused to cut any corners to make sure it was perfect for my Hairbrella community. It is truly the swim cap I wish I'd had growing up. The ones on the market were uncomfortable and made me feel like one of the "Coneheads".
I knew there had to be another way!
Designing something truly thoughtful and innovative to cover our hair hasn't been a priority for the manufacturing industry, but we are changing that – one "Hairbrella" (covering) at a time!
This one is a game-changer! Thanks as always for being the fuel that keeps us going and growing. We appreciate you! <3
