NANO and Nizoral Contain "sodium laureth sulfate"!

[TonyTheTiger]

I noticed NANO shampoo also Contains sodium laureth sulfate, and So does Nizoral Sodium Laureth Sulfate?

I heard this is bad for the hair follicles it actually dries out the stuff inside for some people.



Hair Loss FAQ

Q: Are other analysis of the hair needed?
A: Sometimes microscopic analysis is used to determine if your rate of loss is excessive, if the growing hair bulbs are normal, confirm the presence of fungal infections, or determine the severity of alopecia areata. Mineral analysis may be used to determine imbalances of calcium, sodium, magnesium, and lead. However, today's blood tests are also very sensitive for these minerals.

Q. Have you been shampooing with gasoline or dishwashing detergent?
A. Most likely! Laurimide DEA is used in a shampoo to strip debris and add lather. It is also used in dishwashing detergent. If a person is experiencing hair loss or other scalp problems, it is advisable to avoid chemicals in shampoos such as:

1. Sodium laurel, laureate or laureth sulfate (SLS) sodium dodecyl sulfate (SDS) or ammonium laurel, laureth sulfate or sulfeth which have 7 day ? lives and damage follicles by acting as a degreasing agent. They are a gasoline derivatives.
2. Nitrosol diethelanolamine (DEA) or cocamide DEA - (cancer causing agent)
3. Alpha hydroxy acids - glycolic, lactic or malic acids
4. Ethelene oxide
5. Isopropyl alcohol
6. Mineral oil
7. Sodium Chloride - (table salt causing dry scalp)

These chemicals are found in over 95% of all commercial shampoos. There is evidence that these chemicals actually corrode the hair follicle and impair the ability of hair to grow. SLS seems to cause a dramatic decline in the hair growth cycle, prolonging the hair loss phase (normally three months) by a factor of eight. Simply removing the corrosive and irritating effects of these ingredients begins to restore the healthy function of the hair follicle.

I concur. It is alarming that these consumer grade hair loss products contain additives that can harm hair follicles.


Many don't realize -- these products are designed to do one thing and one thing only -- SELL. Anything that can be done with the formula to make it cheaper to produce, last on the shelf longer, withstand transportation, and smell nicer, will take severe precedence over any of the secondary characteristics of the product. The secondary characteristics are, of course, those that give it any true cosmetic value.

That's the price of depending on commercial products, unfortuantely.

SLS is dirt cheap -- almost free. That's why they use it. There are many healthier alternatives, but the cost hurts the producer's bottom line and makes it less worthwhile to even release the product.

Bryan previously posted a study that indicated that SLS might be 'good' for hair growth!

It's highly amusing to me that there are some old posts on alt.baldspot suggesting that SLS might actually be beneficial for hair growth! Here's one from Kevin Davis:

Cool. In addition, SLS may accelerate hair growth by altering PKC levels -
see below (sodium dodecyl sulphate = sodium lauryl sulfate).

"Induction of hair growth by skin irritants and its relation to skin protein
kinase C isoforms."

Br J Dermatol 1999 Apr;140(4):616-23.

Induction of hair growth by skin irritants and its relation to skin protein kinase C (PKC) isoforms were evaluated. Dorsal skin of BALB/c mice was shaved and anthralin (0.1% in corn oil) was applied on one side of the shaved backs in 20 mice daily for 5 days. The corresponding opposite side treated with corn oil served as a control. In another 20 mice, sodium dodecyl sulphate (SDS, 10% in water) was applied on one side of the shaved backs for 5 days by the same procedure as above and the corresponding opposite side treated with water served as control. Visible acceleration of hair growth on anthralin-treated skin was observed as early as 14 days after the application of anthralin and significant hair growth was observed at about 17-20 days. Enhancement of hair growth on SDS-treated skin was observed at about 3 weeks from the beginning of the treatment. None of the mice showed remarkable hair growth on the control side in either group. Mouse skin PKC isoforms levels detected by Western blot showed a similar pattern in both treatment groups. PKC alpha was downregulated initially, and was then elevated from 3 days after anthralin treatment and 14 days after SDS application. PKC beta was unchanged initially, decreased at 8 and 14 days after anthralin and SDS treatment, respectively, and reverted to the control level at 25 days after anthralin treatment, when it was still lower than the control in SDS-treated skin. PKC delta was also unchanged at first, but was elevated from 3 days after anthralin treatment and 14 days after SDS application. These results suggest that involvement of PKC may be a general phenomenon in irritant-induced hair growth in mice. Considering the stimulatory effect of PKC alpha and inhibitory effect of PKC delta on cell growth, we postulate that PKC alpha may be responsible for enhancement of hair growth while PKC delta may inhibit hair growth to keep the hair growth in balance.

This is Michael Barry's view on the matter:

Shampoos are typically only on the scalp for less than one minute, the laureth sulfates and foaming ingredients therein are surficants and are not designed to penetrate the dermis and to rinse off cleanly with water. They certainly never damage body hair on males, and to suggest they damage head hair is ridiculous with traditional usage. Shampoos are much milder than body and hand soaps. Two shampoos have been shown to increase diameter of hairs and anagen percentages of hairs growing as well as decreases in sebum in tests. One were a class of shampoos that contain the aforementioned ketoconazole and the other contains an ingredient called piroctone olamine.
