SLS(as found in shampoo) and SOD

[Jacob]

First paragraph from the "discussion":

"The demonstration that levels of Cu,Zn-SOD within the epidermis are significantly reduced following topical exposure to irritants strongly suggests that oxidative stress is involved in the inflammatory process. Importantly, as regards our understanding of the mechanisms involved in ICD, this change appears not to be restricted to dithranol, which is known to generate ROS during auto-oxidation, but also extends to chemicals such as SLS, which are not normally directly associated with ROS generation."

This is one reason why I try to stay away from such products- and other irritants. Every little bit of help counts IMO.

SLS...I am assuming you mean sodium laurel sulfate right?

Do you know of any quality shampoos or hair care products that don't have it as an ingredient?

I also want to state that most shampoos, the VAST majority of them have SLS in them.

I think SLS can cause irritation of the scalp, but I don't think that SLS in any way causes hair loss. If this were the case, how do you account for those people who never suffer from alopecia and yet use SLS containing shampoos all of the time?

I do think however that it can't hurt if you use a shampoo that doesn't contain SLS, I just wouldn't go out of my way to look for one. I'm not sure if my own favorites, Revivogen Shampoo, Nizoral, H&S, etc. , have it or not, but even if they did I think the benefits outweigh the potential disadvantages.


Nonetheless, if it bothers anyone that a shampoo has SLS in it, there probably are good alternatives.

There are quite a few companies putting out SLS-free products out there. The ones I use and like are:

http://www.morroccomethod.com/
My fav: http://www.sweetsunnah.com/cgi-local/cc ... rt=20-0011
http://www.lamasbeauty.com/hair.html

I know you can get the Morrocco and Lamas at other places besides their website.

It may not cause hair loss but it may not help either. We use SOD mimetics and here we have a substance- SLS- that may decrease SOD levels. I always thought this was important for those with hair loss?? Those who don't have any hair problems probably don't have to be as concerned- maybe their hair/scalps aren't as sensitive.

As long as there are good SLS free shampoos out there...

I'm not sure if my own favorites, Revivogen Shampoo, Nizoral, H&S, etc. , have it or not, but even if they did I think the benefits outweigh the potential disadvantages.

Nizoral : Ingredients: 1% Ketoconazole, Water, Sodium Laureth Sulfate, Cocamide MEA, Sodium Cocoyl Sarcosinate, Glycol Distearate, Acryl Acid Polymer (Carbomer 1342), Fragrance, Sodium Chloride, Tetrasodium EDTA, Butylated Hydroxytoluene, Quaternium-15, Polyquaternium-7, Sodium Hydroxide and/or Hydrochloric Acid, FD&C Blue No. 1.

Revivogen: Ingredients: distilled water, disodium laureth sulfoccinate, cocoamphocarboxyglycinate, cocamide MEA, aloe vera, jojoba oil, cocoyl sarcosine, dimethicotone, glicole etilenico stereate, polyquaternium-4, pantenolo (vitamin B5), saw palmetto extract, niacina, guar, soy proteins, vitamin B6, silk proteins, allantoina, vitamin C, alpha-linolenic acid, gamma linoleic acid, linoleic acid, zinc sulfate, azelaic acid, menthol, benzophenone-4, methyl paraben.

So Nizoral contains SLES (in low percentage), but not for this it
produce inflammation (or things like this)... indeed... it
comes purposely used in order to fight inflammation, dermatitis, etc

Revivogen does not contain neither SLS neither SLES
just for chosen of the producer... revivogen is in fact one of
the best ones shampoo in the world !

Akira, thanks for listing all that info! There you go, Revivogen shampoo is a great shampoo, I agree. I am using it pretty much every day now.

no problems Sam
...returning to the shampoos...there are many many shampoos that does not contain SLES or SLS, but this does not imply that those shampoo (without sles or sls) are delicate or less harmful or less damaging than one which contains Sls or Sles ...
it depends much by the combination of the various ingredients and by the percentages, beyond that by others surfactants, by the type of conserving and by the number of coloring ...
there are many elements to judge a shampoo

[Jacob]

Akira...I'm sure there are some shampoos- "natural" ones..that could be "harmful" etc. But most, especially the ones I use, are no where near anything like those containing SLS etc.

There is actually one I use that contains SLES..here are a few things the company had to say about this:

Our shampoo contains Sodium Laureth Sulfate (SLES) and C14-C16 sulfonates as the detergent base, and not Sodium Lauryl Sulfate (SLS). The phosphatidyl inositol enriched phospholipid profile is formulated into mixed micelles. In mixed micelles, detergent molecules are restricted. Mixed micelles moisturize the scalp instead of drying it. The shampoo includes many other ingredients including witch hazel bark oil/water extract (not with alcohol), green tea oil/water extract, and other ingredients that are great for deep cleaning oily, itchy, and dandruff scalps. The shampoo reduces hair tangling which may reduce hair loss induced by brushing tangled hair; it makes the scalp feel very good and the hair look thicker.


Anyway it is not SLS but SLES, Sodium Laureth Sulfate (a different material than SLS), which we have in our product. SLES is a naturally-occurring cleanser derived from coconut oil and is widely accepted and is used in most shampoos, including baby shampoos.

Detergents are the common denominator in all shampoos; the differences between shampoos are in the rest of the ingredients, and in the formulation technologies. In our mixed micelles, the mode of action of the detergent is modified from that of a common shampoo. The product becomes a moisturizing shampoo with no need for a conditioner after the use of the shampoo

So I do rotate that shampoo with the many "natural" ones I use. It's called Micellarin Green: http://www.elsomresearch.com/shopping/p ... oo-026.htm

[Akira]

OK. Now I have seen Micellarin Green; it is a product interesting ... thank you for the segnalation !
Anyway my message was direct in general, I was not referring to you in particular

SLS (Sodium lauryl sulfate) is among the worst surfactants, no doubt about it
SLES (Sodium laureth sulfate), alone (like in Micellarin Green), is a mediocre surfactant, not bad surely, very effective; so your prodoct is great under this point of view...

but in the previous message I only was trying to draw the attention on the combinations...sometimes damaging... anyway the "riskiness" ( only "on the paper" if used alone ) of SLES (and SLS too) certainly increases if it has associated (among the ingredients) with the COCAMIDE (DEA-MEA-MIPA).
In fact COCAMIDE, in combination with some surfactants (SLES and by-products ), strengthens negative effects at aesthetic level (the solution gets more aggressive) and at tossicologic level (they free Nitrosamine)...

Then there is not doubt that almost always is better a shampoo without Sles (and above all Sls) than one which contains it; ). But attention to all the INCI

[Jacob]

I didn't think it was directed at me...but I like to defend my naturals LOL.

This is something else the company said...ties into what you're saying there:

There is a concern that some ingredients like TEA which are commonly used in conjunction with SLS may - under oxidating conditions - contribute to the formation of nitrosamine which is a carcinogen. Addition of anti-oxidants such as Vitamins A, E, or C prevents the formation of nitrosamine.

Micellarin Green is the only shampoo I use where I almost have to wash...then rinse and repeat. It won't lather much on the first wash..but it lathers nicely on the second. I think they mention that on their website as well. And I don't think that's a bad thing really...it's a unique shampoo.
