Pode Levar Aerossóis de higiene e sprays no Avião? (Regras TSA / EUA)

Sim, em frascos de até 100 ml (3,4 oz), dentro de um saco plástico transparente de 1 litro.

Sim, líquidos e produtos de higiene em embalagens maiores são permitidos na mala despachada (limites de aerossol).

Standard carry-on baggage size allowances apply; TSA publishes no individual numerical cap for personal use.

Standard toiletries and liquids conforming to the 3-1-1 rule (containers under 3.4 ounces / 100 ml inside a clear quart bag) require no separate declaration. You simply place the bag in a screening bin. Medically necessary liquids exceeding 3.4 ounces must be verbally declared to checkpoint screeners before inspection.

If liquid containers exceeding 3.4 ounces (100 ml) are detected in carry-on baggage without an infant or medical exemption, screeners will not allow them past security. Travelers must surrender the item for destruction, return outside security to place it in checked luggage, or mail it home.

Yes — aerosol dry shampoo follows the liquid rules: 3.4 oz or less in your liquids bag for carry-on, bigger cans in checked luggage within the FAA aerosol limits (≤ 18 oz each, 70 oz total).
