Pack for the vacation you are going on and keep your toile bag organized.

Spending whole days by the pool calls for something different than moving to a new place to stay every few days. Choose a hairstyle and routine that you can quickly manage yourself, even if you have an early train to catch. A daily blow-drying session does not belong on your vacation checklist. Bring the products you use at home, in small bottles with labels, and put them together in a separate bag. That way, a leaking cap won't take your entire suitcase. If you are traveling with hand luggage, check your airport's current liquid regulations in advance. Your trusted brush or comb and a few hair accessories are more useful than three extra styling products. If there is a hairdryer in the room, that saves space in your suitcase.

Give your hair a place in the shade too.

De American Academy of Dermatology on summer hair care describes that sunlight can make hair drier and more brittle. Their solution is nice low tech: a hat with a wide brim and into the shade occasionally. So place that hat next to your sunglasses, and choose one that you actually wear.
