Have used 28oz size for years. I’ve found Amazon travel size a little pricey for me. If I could have gotten shampoo at local store I would have. One set of travel is equivalent to a 16 or 28 oz shampoo alone. “ LOWER YOUR PRICES “My son travels for wrestling and these are FANTASTIC for his travel shower bag! Lasts him all week/weekend and smells great! Definitely recommend!Smells fantastic but the package was damaged and the product leaked out inside. I lost over halii ProductI bought this for my trip to Argentina. I would not use this brand long term since I have to swap products often to keep my hair happy. I do recommend this if you are travelling though due to the size. It does what it needs and if you are like me having to do things short term it is perfect. Great for keeping in the shower for guests too.To travel outside the statesI bought these for a trip, I don’t know what the average shopper of these particular items are looking for.The security had no complaints with these.They made the trip in one piece.They did their job when it came time to use them.No complaints, I’ve used this brand in the past and no real preference. They did what they needed to do and I was happy to find shampoo and conditioner paired.The product is fine, but the top of the conditioner bottle came loose and leaked into the package.Great for traveling looks like a perfect size for a long weekend. Only complaint the price, I just saw these at my local target for .99.
