Days for Girls is turning periods into pathways.

We increase access to menstrual care and education by developing global partnerships, cultivating Social Entrepreneurs, mobilizing volunteers and innovating sustainable solutions that shatter stigma and limitations for women and girls.

Increase access to menstrual supplies

Cost-effective, safe, sustainable and contextually relevant products help women and girls manage their periods and engage in livelihood activities.

Shatter stigma through education

Access to timely, factual information about puberty and menstruation can lead to increased body literacy, a healthy public perception of menstruation and decreased stigma and shame.

Elevate menstrual health

Menstrual health and hygiene are critical factors in improving education opportunities and livelihood outcomes for menstruators worldwide.

Advocate for global policy change

Lasting change occurs when menstrual health is prioritized and integrated into regional, national and international policy goals.

Our theory of change

By combining innovative menstrual health solutions and education with Social Entrepreneurs and volunteers we advance locally driven policy and advocacy to create long-lasting impact.


We’ve impacted the lives of more than 2 million menstruators in over 144 countries


How it all began

Days for Girls began in 2008 when Founder and CEO, Celeste Mergens, was working with a foundation in Kenya assisting an orphanage in the outskirts of Nairobi. In the wake of historic post-election violence, the population at the orphanage had swelled from 400 children to 1,400.

Upon inquiring about the menstrual health practices of the many girls at  the orphanage, Celeste learned that many  were sitting on cardboard in their rooms for several days each month –  often going without food unless someone would bring it to them. This set into motion her first intervention: disposable pads. But Celeste and her team quickly discovered that  without any place to dispose of the pads, this was not a viable or sustainable solution. 

It was time for plan B: a washable, long-lasting pad.

The first Days for Girls Kits were quite different from the design we use today. Each of the 30 iterations that followed would be informed by extensive feedback and designed to meet unique cultural and environmental conditions in communities throughout the world. It quickly became clear just how powerful menstrual health solutions are in helping menstrual women and girls break the cycle of poverty and live their lives with  dignity.

Our next step was to develop a health education curriculum that would be included in each DfG Kit distribution. With user-centered product design and curriculum in place, the final stage was to launch a Social Entrepreneurship program that enables local women to start their own Days for Girls businesses – and serve as vital thought leaders and suppliers within their own communities.
