Why Is My Hair So Dry?
Here are the common causes
of dry hair

Dry hair can be a seasonal problem: your hair is affected by the weather – whether that means shifts in temperature or the merciless summer sun. A dry atmosphere can strip the hair of moisture and make it feel even dryer, more brittle, and dull. Dryness can also lead to unwanted frizz, a straw-like consistency or broken hair, making it extra challenging to style.
Another cause of dry hair is over-washing with non-caring formulas and excessive blow-drying. Over-washing has a stripping effect on the hair. The repeated expansion and contraction of the hair shaft as it’s soaked and dried, soaked and dried, ends up drying it out. In the same way, blow-drying hair on a high heat and speed setting can also lead to dryness and damage, since the hair is at its most fragile when wet.
If you have a dry scalp, you might have dry hair too – particularly if your scalp is not producing enough natural oils to lubricate the hair. An irritated scalp that ends up shedding and peeling can also lead to dry hair. In addition to external aggressions, internal issues like poor diet, hormonal changes and aging can also be contributing factors to a dry scalp and dry hair.
What Causes Dry Ends?

While dry ends are sometimes just an extension of unhealthy hair at the root, they are generally a sign that nutrition isn’t getting from your roots to your ends. Of course, sometimes you can get dry ends because of over-drying and styling your hair on a high heat setting or speed. Whatever the cause, dry ends require extra moisturising care, or they can lead to even more damage – the dreaded split ends and broken hair.
How to Treat Dry Ends?

You can fix dry ends – and prevent split ends from forming – with deep conditioning. Apply a hair mask or a hair oil just to the ends of your hair as an added part of your hair care routine. If the situation has already gone too far, discover these ideas on how to get rid of split ends.
The Best Ways to Treat Dry Hair

Before you ever feel your hair becoming dry or frizzy, there are preventative measures you can take to ensure your hair stays hydrated and healthy. Here are our top 5 tips for preventing dry hair:
1. Trim your hair regularly to keep the hair strands healthy and help avoid dry ends and split ends.
2. Avoid washing and drying your hair every day with non caring shampoos (don’t worry, at Kérastase, we have only developed caring shampoos with your hair in mind). When you do wash your hair, use hydrating shampoos and apply conditioner after shampooing.
3. Wrap your hair instead of air drying or heat drying. Avoid rubbing your hair with a towel or immediately drying it while it is still wet. This stretches the hair to breaking point.
4. Avoid heat-styling tools and use heat-protectants such as sprays, milks, serums and gels whenever you do heat style.
5. Deep condition weekly with hair masks and hair oils, or overnight serums, and use leave-in treatments, which can add even more moisture to your hair.

The Best Ways to Prevent Dry Hair
Sometimes a simple trim will fix dry hair at the ends, however, if you have dry hair from root to tips, there are a few things you can do to hydrate your dry hair, and even treat and repair that dry hair.
When you do wash it, use products that have fewer stripping detergents. If you’re not already using one, introduce a conditioner or conditioning mask into your weekly routine to deliver more hydration to your hair.
You can also condition with hair oils, which nourish and moisturise your dry hair.
