How can I tell if my post-vacation hair needs hydration
or moisture?
Stephan from the Leonor Greyl Institute addresses this issue,
which many women face every day.

How to recognize a dehydrated hair?

“You can tell when hair is dehydrated because it’s porous: it puffs up in humid weather,
gets frizzy and looks dull.
Every hair type needs hydration to keep the hair’s cuticle smooth.
With a water-based formula, Tonique Hydratant is the hydrophilic product par excellence.
Styling products such as Sérum de Soie Sublimateur or Condition Naturelle can also
work well.
And for very dry hair, nothing beats Crème aux Fleurs, a washing cream left
in for 10 to 20 minutes before rinsing.

Moisturize thicker hair

Hair that is very thick, brittle, with split ends needs a richer, oil-based product.
But remember that water is still essential for carrying moisturizing agents,
so very damaged hair needs to be hydrated before it is moisturized.
For this, I spray some Tonique Hydratant and wait for a few seconds for the hair
to absorb the product, then I apply Huile de Leonor Greyl or a deep repairing
treatment left in for up to 20 minutes.
Éclat Naturel styling cream is a great finishing touch, as it gives hair all the nutrients
it needs from root to tip.

Generally speaking, thick hair needs more deep moisturizing treatments than finer hair,
which can be weighed down by rich products and prefers regular hydration instead.”

Visit your stylist regularly for advice and to remove any tips that are too damaged
to be treated — the last resort for getting rid of split ends and brittle hair!
