hair grow faster in humidity

Have you ever noticed that when you travel to a humid climate, your hair seems to grow faster? Or maybe on a particularly humid day, you feel like your hair is growing at record speed? The idea that humidity can affect hair growth is a common one, but is there really any truth to it?

To understand the relationship between humidity and hair growth, we must first understand the basics of hair growth. Our hair goes through three phases: the anagen phase, the catagen phase, and the telogen phase. During the anagen phase, our hair follicles are actively growing our hair, while the catagen and telogen phases are resting and shedding phases, respectively.

The anagen phase, also known as the growth phase, can last anywhere from two to seven years, depending on factors such as genetics, age, and overall health. During this phase, the hair strand is continuously growing, but the rate of growth can vary.

So, how does humidity play a role in this process? Humidity refers to the amount of water vapor in the air. When the air is humid, it contains a higher level of water vapor, which can affect our hair in several ways.

One way humidity can affect hair growth is by keeping the scalp hydrated. Our scalp produces natural oils that keep our hair follicles healthy and nourished. When the air is dry, these oils can evaporate, leaving our scalp and hair feeling dry and brittle. This can lead to hair breakage and slower growth. On the other hand, when the air is humid, the moisture in the air helps to maintain the oils on our scalp, creating a healthier environment for hair growth.

Additionally, humidity can also increase blood circulation to our scalp. When the air is humid, our pores and blood vessels dilate, allowing for better blood flow and nutrient delivery to the hair follicles. This increased blood flow can support and stimulate hair growth.

Another way humidity can promote hair growth is through adding moisture to the hair strands themselves. As mentioned earlier, dry air can cause hair to become brittle and prone to breakage. Humidity can help to keep our hair hydrated, making it less likely to become damaged and promoting healthier and stronger growth.

However, it’s worth noting that while humidity can contribute to a healthier environment for hair growth, it’s not the sole factor. Genetics, hormones, and a healthy diet all play crucial roles in hair growth and cannot be ignored.

On the other hand, a high level of humidity can also have some negative effects on hair growth. Too much humidity can make the hair prone to frizz and can make it difficult for hair products to penetrate the hair shaft. This can lead to product buildup and hinder hair growth.

It’s also essential to consider the type of hair when discussing the impact of humidity on hair growth. Those with curly or wavy hair may experience greater benefits from humidity, as their hair tends to be drier and more prone to breakage. However, those with straight hair may not see as great of an impact.

In conclusion, while humidity can play a role in hair growth, it’s not a direct cause. Maintaining a healthy scalp and hair routine, including a balanced diet, is still the most crucial factor in promoting hair growth. However, keeping our hair and scalp hydrated, blood flow stimulated, and hair strands moisturized can all contribute to healthier hair growth, which humidity can assist with. So the next time you’re in a humid climate and notice your hair growing faster, you’ll know that it’s not just your imagination, but rather a combination of factors at play.
