As beauty editors, we’ve heard our share of beauty myths. That’s why we decided to start Beauty Mythbusters, a series where we ask experts to debunk common misconceptions and questionable beauty beliefs . 

To start us off, we’re discussing whether or not hair really grows faster in the summer. We spoke with certified trichologist Penny James to find out the truth. 

Does your hair grow faster in the summer?

The truth is, there is no evidence that suggests our hair grows faster as a direct result of the changing season. That being said, James says that during the summer months, some people might change their eating habits to be a little healthier and this can play a role in the appearance of your hair. “Due to healthier eating habits, your hair will look fuller, shinier and can maybe grow a little faster,” she says. James mentions that as long as you don’t over-expose your hair to chlorine, sea salt and the sun, your hair will stay healthy and strong. 

What are some things you can do to help make your hair grow faster during the summer and beyond?

“Wearing a hat outside is one of the best ways to protect your hair and scalp from the UV rays,” says James. If your hair is dull and dry, make sure to use a hair treatment to help restore your strands and make them shine. We love the Garnier Fructis Nourishing One Minute Hair Mask for its ability to nourish our hair in just one minute. Other tips James recommends is to avoid heated styling tools as much as possible and when going to the beach, apply a deep hydration mask all over the hair and wrap it up to keep it fully protected from the sun and dehydrating salt water. 


Year-round, James recommends sticking to a balanced diet that’s rich in protein. Another tip is to try managing your stress levels. Living in a high state of stress can affect your  hair and it’s growth process. And most importantly, manage your expectations. “Your hair can grow up to a half an inch per month if you’re not suffering from any kind of underlying health issues,” she says. So note that while these tips can be helpful, hair growth is a process.
