Generally, it’s not  advised to change shampoos with the seasons, but it could benefit some people according to their hair type and climate.

In winter, the hair tends to be drier compared to other seasons and due to hot water, the scalp also becomes drier. It leads to dry and brittle hair, so some people switch to the moisturising shampoo during colder weather to help their hair stay smooth.

During summer, the scalp produces more oil due to sweating and humidity. In this case, switching to a clarifying shampoo can help remove excess oil and build-up.

Switching shampoo depends on your hair and the condition you have. If you have any doubt about it then you can take advice from a dermatologist.
