In one of my recent Birchbox packages was a sample of Number 4 Lumiere Hair Mask.
I slept on this stuff until last night. I mixed it in with my favorite moisturizing conditioner because it's a reconstructor. My hair turned out fabulous and now I'm stung.
I checked the price on Birchbox and they sell it for $58, but I've got points to take about $10 off. I used all of the sample size, so I don't know how well it works alone. I justify the cost by telling myself I wouldn't be using it as regularly as my normal moisturizing. I had a dream about the stuff last night, so it'll probably find its way into my life really soon.
Another item I've been eyeballing for a while (about a year actually) is the Kerastase Chronologiste. I haven't given in yet, still strong.
I would like to dabble a bit more in Ayurvedic haircare because I've not seen any negative feedback from anyone.
Also, scalp massages more consistently.
