Buying Notes
Follow TSA limits (3.4 oz / 100 ml for carry-on liquids). For carry-on travel choose TSA-sized bottles or solid bars to avoid leaks or checked-bag dependence. If you use topical treatments, decant small, labeled bottles so application stays simple. Bars save space and avoid liquid rules but need a dry container to last. Prioritize the same active ingredients you use at home to reduce change-related irritation; when in doubt, test a travel size before longer trips.

Frequently Asked Questions
Are shampoo bars TSA-friendly?
Yes — solid bars are not subject to the 3.4 oz liquid rule and are ideal for carry-on, but store them dry between uses.
How many mini bottles can I bring in carry-on?
You can bring multiple bottles as long as each is 3.4 oz (100 ml) or smaller and they all fit in one clear quart-sized bag.
Should I match the exact product when traveling?
If maintaining a routine is important, use the same product format (liquid vs bar) or the same formula when possible to avoid scalp changes.
How do I store a shampoo bar while traveling?
Use a ventilated tin or slotted travel case so the bar can dry between uses and won’t turn mushy.
Can I decant treatments into travel bottles?
Yes—use clearly labeled, leak-proof 100 ml bottles and keep them in your carry-on with other liquids.
