We've all been there. Shiny, manageable hair in the spring, then suddenly duller, drier, or falling out more without having changed anything in our routine. It's not just our imagination. Hair reacts very strongly to the seasons, and it's completely physiological.
Understanding why they change allows us to stop feeling guilty, to adjust our actions at the right time, and above all, to avoid putting them through unnecessary things.
Hair is directly influenced by our body and our environment
Hair is dead matter, but it is directly affected by what happens inside our body and by our environment.
They are reacting in particular to:
• To hormonal fluctuations
• The outside temperature
• Air humidity
• Sun exposure
• To changes in lifestyle
With each change of season, several of these parameters change simultaneously. As a result, the hair adapts, sometimes clumsily.
Autumn and spring
It's often during these times that we panic. No more hair in the brush, in the shower, on the clothes. Yet, in most cases, it's a normal phenomenon.
For what ?
• The hair life cycle is influenced by light
• In summer, the growth phase is prolonged
• In the fall, these hairs gradually enter the shedding phase
• In the spring, this renewal becomes more visible
This is known as seasonal hair loss. It is diffuse, temporary, and reversible. It does not mean that fewer hairs will grow back, simply that they are renewing themselves.
Winter
Winter is often the most difficult season for hair fibers.
There are multiple reasons:
• Cold slows down microcirculation in the scalp
• Heating dries out the ambient air
• Repeated friction from coats and scarves weakens the fiber
• More frequent washing with hot water can unbalance the scalp
As a result, the hair becomes drier at the ends, sometimes duller, while the scalp may become uncomfortable or reactive.
Summer
Summer often gives the illusion of more beautiful hair. It appears lighter, fuller, and more textured. But behind this immediate effect lies a more complex reality.
What hair really goes through in the summer:
• UV rays degrade keratin
• Salt and chlorine open the scales
• Dehydration weakens the fiber
• The scalp may produce more sebum to protect itself
Adapt your routine
When hair changes, the reflex is often to use more products or completely change your routine. This isn't always the best solution.
The main thing is to:
• Respect the natural rhythm of the scalp
• Adjust washing frequency according to the season
• Strengthen the scalp during periods of hair loss with a serum, for example
• Protect the fiber during periods of harsh weather
Seasonal hair changes are a reflection of a living organism adapting to its environment.
Understanding these mechanisms allows us to make better decisions, avoid excesses and above all to approach each season with a smarter, more respectful and more efficient routine.
