Hair growth in the summer is a myth that’s been told for years and years.
The short answer to this question / myth is no: the summer sun does not make your hair grow longer.
But don’t get too bummed out just yet.
When you are exposed to the summer sun, you are getting more Vitamin D and your estrogen levels naturally increase.
Many women also let their hair go lighter for summer, either naturally or by getting highlights from their stylist. And lighter hair, especially if lightened by the sun, can give the illusion that your hair is growing faster.
In addition to more fun in the sun and more blondes at the pool, more people are eating more fresh fruits and vegetables during the summer months. Hey – we want to feel and look great in our summer bikinis and boost our energy for summer vacations and camping trips, right?
Even though your hair doesn't grow longer in the sun, too much sun exposure can lead to thin and damaged hair!
