This is one of those products that I've almost bought countless times over the years. It's probably the most well known Bumble & Bumble product and yet as many times as I got close to buying it, I never did. Until recently ^^
First impression was the packaging, as I had ordered online I hadn't seen it beforehand but for some reason I'm in love. I assumed it'd be a plain plastic bottle, but it's kind of flexible and rubbery? I later found out through some Bumble & Bumble trivia that it's made out of the same material as scuba gear (or something along those lines) Obviously this makes no difference to the products at all but I feel it adds a nice touch.
I have tried other (much cheaper) salt sprays in the past and assumed they'd all be about the same, and when those didn't do much for me it put me off trying this one. However I have to say this is a lot better than any of the cheaper alternatives I've used. You spray it (rather liberally I've found) or damp hair. It then says you can let it dry in the wind or give it a blow dry. I actually just tied my hair up in a messy bun and went to sleep, and I found that worked nicely.
I do have a natural wave to my hair that's become less noticeable now my hair's longer and weighs it down (and has probably been forced in to submission by daily straightening) so I'm not sure how much difference this would make if your hair is naturally poker straight. However for me it definitely enhanced my waves and made them a lot more obvious and more curly and I got quite a few compliments on my hair that day.
However it did start to fall flat throughout the day, it didn't go straight (my hair is physically incapable of going straight without a lot of heat abuse) but it wasn't as bouncy after a few hours. I also have dry and damaged hair that's kinda frizzy and unsurprisingly this enhances that, especially after I've walked to work and it's been blown around a bit. I'm used to sleeker styles and will probably mess around with this a bit more and possibly try and straighten the top a bit and find a way to make it work for me and look less frizzy (and see if I can find a way for the hold to keep longer) but at the end of the day it's a salt spray and a messy flyaway look is what you expect. I'm just hoping to find a way to make it look a bit more wearable for every day use.
It definitely delivers on the beach waves promise and does it far better than cheaper alternatives so if that's the look you're after I'd say it's worth the price tag.
