Almost every year in late June, the same question arises in our barbershop. One of our regulars takes the place in the chair, looks into the mirror, and claims his hair has taken over his entire head since the last haircut. The hot summer days are finally here, and it turns out that men cannot survive without a haircut every two weeks instead of the traditional four.
Our clients at First & Mane say that very often, and, in the majority of cases, they turn out to be right. Indeed, when the weather is nice, men go out, become healthier, and their hair grows faster.
But is there any scientific evidence to prove this assumption? Having seen thousands of haircuts, we decided to analyze this issue. Today, we are going to explain how your follicles react to rising temperatures, especially if you are looking for a Scottsdale, AZ, barber shop near you.
The Process of Natural Hair Growth
It is impossible to discuss the impact of weather on hair growth without understanding how hair grows naturally, including the common question, does hair grow quicker in the summer? There are three stages that a hair follicle goes through before becoming visible on the head. The first phase is the anagen phase. This is the stage when hair follicles grow actively. It takes two to six years for one hair to reach the end of this cycle.
Next, it is replaced by the catagen phase. This is a short transitional period when hair stops growing and detaches from the bloodstream. The final stage is the telogen phase. During this resting period, hair follicles remain inactive for several weeks and fall off, allowing for new hairs to start growing.
The whole cycle depends on different external and internal factors. Of course, genetics plays the leading role in this process. Still, your diet, hormonal balance, and the overall state of your health also affect how healthy and fast-growing your hair is.
The Influence of Summer Weather
In the summer, everything changes around you, and your organism reacts to it. Firstly, the sun becomes brighter, and you spend more time outdoors under direct sunlight. Thanks to this, you obtain more vitamin D. This specific vitamin helps you to create new hair follicles. Increased levels of this substance can even activate dormant hair follicles and force them to enter the growth phase, which helps explain the question of…do hair grow faster in summer?

To achieve this goal, your cardiovascular system pumps a lot more blood to the skin surface, including your scalp. In such a way, you receive increased oxygen levels in the hair follicles.

While there is some evidence for faster hair growth during summer days, it is hardly strong enough to change your styling routine entirely.
