Do you follow the lunar calendar to care for your hair? Here we describe each phase and what it does to your hair. Did you already know this information?
The lunar calendar, historically used in agriculture and health, has also gained relevance in hair care.
In 2025, many people still associate the lunar phases (new, waxing, full and waning) with benefits such as hair growth, strength and nutrient absorption.
Although there is no scientific evidence to support this practice, its popularity is based on traditional beliefs and the idea that, like the tides, the moon influences the human body, especially when natural treatments are combined on key dates.
What is the lunar calendar for hair used for?
According to Kate Wilson, Chief Operating Officer of Hairlab, a hair care company, many of its consumers follow the lunar calendar to decide when to cut their hair and apply moisturizing treatments that enhance its health and appearance.
“These ancestral traditions are often combined with advances in hair technology and science, through the use of products made with natural ingredients such as aloe vera, avocado, carrot, jojoba and wheat germ,” says Kate.
“This makes them the perfect complement for those who want to take advantage of these dates to nourish, revitalize and strengthen their hair in a comprehensive way,” she added.
According to the Lunar Calendar 2025, these are the recommended dates for cutting and applying hair treatments:
- Crescent Moon: Ideal for haircuts that promote fast and strong hair growth , as well as moisturizing treatments that stimulate the hair follicle. Recommended dates: February 6, March 7, April 4, May 5, June 3, July 6, August 4, September 3, October 2, November 30.
