🩷 Welcome to Rerein

Making girls' health make sense.

Girls' don't need 'more' health information. There's already a LOT of it. We need to get better at translating it into something that actually makes sense in the context of real life.

There's a gap between: “Oestrogen fluctuates throughout the menstrual cycle” and “Why did I feel amazing three days ago and now I want everyone to stop speaking to me?!”

How we can help

Girls don't always have the words.
Parents don't always have the answer.
Schools don't always have the resources.

The why behind what we do

Girls' don't need 'more' health information. There's already a LOT of it. We need to get better at translating it into something that actually makes sense in the context of real life.
