To those wanting only a 1-3 day hold that comes loose easily with water, what if something gets in the way of your super regular detach session? Say you have to stay at a friend's house for a few days or someone close takes ill or you go for a weekend break away. Knowing my hair was attached with such a fragile bond that could come loose at any point would make wearing a nightmare for me. You can't always plan out every day ahead and you won't always be at home when the system needs rebonded if it's happening every other day.
