Sebastian Potion 9 hair styling treatment

September 29, 2009 Reviewed by Marta 2 Comments
I've really been focusing on my hair over the last few months and have, thankfully, found that good shampoos and treatments - with as few chemicals as possible and with the aim of helping to combat thinning hair - have started to have an effect. I am definitely noticing less hair in the shower drain and I take it as a very good sign that I am now starting to lust after styling products - it means I like my hair again and want to play with it. So when I saw Sebastian Potion 9, I was intrigued by the claims that it was a treatment as well as a styling aid. This could mean that it might contain ingredients that do more good than harm.

On balance, this turned out to be a good guess.  The '9' refers to a line up of botanicals. There is useful wheat protein and macadamia, which is full of fatty acids, as is rose hip. Evening primrose is a source of gamma linoleic acid (GLA), which helps maintain stratum corneum cohesion and reduce transepidermal water loss. Other sources of GLA include borrage, another one of our 9. A few of the botanicals are just so so: such as babassu oil, which is about 70% lipids and is increasingly being used as a substitute for coconut oil.

Although many of the remaining ingredients are benign things, there are a few additions that the 9 will find it had to stand up to. In addition to ubiquitous parabens, there is a controversial ingredient. Octylmethoxycinnamate is a sunscreen that can create biochemical changes that cause mutation and cell death upon exposure to sunlight (which is likely when used as a sunscreen ingredient); immunotoxicity and photoallergic effects; reproductive toxicity that leads to estrogenic effects; organ system toxicity, especially in the liver; and enhanced skin absorption. It should be used with caution by pregnant women and children.

There are also a handful of colorings that attract their fair share of researchers trying to establish which side of the good and evil fence they are on. FD&C Red 40 was once thought to be carcinogenic. These fears appear to be unfounded, although this dye (as a food additive) is associated with hyperactivity in children and it can cause allergic reactions and skin rashes. Annatto has been linked with many cases of food-related allergies, and is the only natural food coloring believed to cause as many allergic-type reactions as artificial food coloring.

Taken as a whole, it isn't that bad. But the 9 really aren't compelling enough to outnumber my doubts. For the time being, I'll stick with John Masters Organics styling gel.

    Would you mind detailing your new hair regimen? I know you've probably reviewed all the products you use, but it would be great to see what's working for you now all in one place.
