Why is our hair more greasy in summer?
Summer is the season for sunny delights, beaches, and outdoor getaways. But have you noticed that your hair gets greasier during this time? Why does this happen, and what can you do about it?
In this article, our expert Julie Pernet reveals the hidden reasons behind this summer phenomenon, its impact on the scalp, and recommends effective and essential solutions to keep your hair fresh and impeccable all summer long.
Causes of Excess Sebum in Summer
1. Heat and Humidity
One of the main reasons our hair gets greasier in summer is the increase in heat and humidity. These conditions stimulate the sebaceous glands, causing them to produce more sebum to protect the scalp and hair. While this increased sebum production is a natural response to prevent dehydration, it leads to a feeling of greasy and heavy hair.
2. Perspiration
Perspiration is inevitable in summer. When we sweat, the mixture of sweat and sebum can clog the scalp's pores, increasing the greasy sensation. Moreover, perspiration attracts dirt and pollutants, further worsening the condition of our hair.
3. Frequent Washing
In summer, it's tempting to wash your hair more often to get rid of sweat and dirt. However, too frequent washing can strip the scalp of its natural oils, prompting the sebaceous glands to compensate by producing even more sebum. This is a vicious cycle that can make your hair even greasier.

Impact of Excess Sebum on the Scalp
Excess sebum has several negative impacts on the scalp and hair. It can cause itching and irritation of the scalp and promote the proliferation of bacteria, which can lead to problems like greasy dandruff. Furthermore, an overly greasy scalp can weaken hair follicles, leading to hair loss. For these reasons, it is crucial to maintain a balance in sebum production, especially in summer.
Our Recommendations
1. pH5 Shampoo
The pH5 shampoo is specially formulated to maintain the pH balance of the scalp. A balanced pH is essential for regulating sebum production and preventing irritation. This shampoo, free of silicones, sulfates, and endocrine disruptors, gently cleanses while preserving the natural oils necessary for healthy hair.
2. Detox Mask
The detox mask is ideal for purifying the scalp and eliminating excess sebum and accumulated impurities. Enriched with natural ingredients, it helps rebalance the scalp's microbiome without drying it out. Using this mask once a week can help maintain healthy hair.
3. Powder Dry Shampoo
The powder dry shampoo is an excellent way to refresh your hair between washes without wetting it. It absorbs excess sebum and adds volume to flat, greasy hair. With a lightweight formula that leaves no white residue, it is ideal for frequent use in summer.
