Core tip: some people think that add oil shampoo can cause hair loss, hair loss, but in fact, silicone oil can be smooth hair scale, reduce the friction damage hair, but at the same time can cause hair coarse, weight change, make the hair becomes dry and appear flat, fluffy,ghd sale australia and does not cause hair loss and hair loss.

Gossip: shampoo containing silicon, can make the person of hair loss, hair loss, itchy scalp.Hair after washing is carried out the slippery, because in shampoo to add silicon or two methyl siloxane and other chemical component, the component is the role of the hair between the void fill, and the smooth touch.But silicon itself impervious and other inert, also closed pores, resulting in the scalp is also easy to itch, hair loss, hair loss may even be complicated by the sequelae.

The truth: that shampoo containing "Silicon", is actually not containing silicon, but refers to a silicone oil (Dimethicone) two.(two) the silicone oil is liquid temperature of the poly two methyl silsesquioxane (PDMS) name, also known as "silicon".With the polymerization degree increasing, there will be a solid PDMS.No matter how they state, all PDMS there is a kind of material, have the same structure:

Poly two methyl silsesquioxane (PDMS) chemical structure

This determines the structure of PDMS is a kind of "inert" material, that is to say it is very stable chemical properties.Since the last century fifty's, silicone oil to personal care products in water, then head get chubulai.Since 70 time, PDMS began to reside in the shampoo and hair care products, rob has thousands of years history of application of vegetable oil, cetyl alcohol and other ingredients style.

The reason why we have to use silicone oil?

Hair from scalp hair follicles of birth, is the main ingredient of keratin.The hair above the amplification, uneven cuticle (hair) is clearly visible, like a fish in general.Shampoo is to remove the hair and scalp dirt and excess oil, but water and decontamination with anionic surfactant can let a hair to produce a series of change: the hair moist water swelling, soft, usually attached to the hair of small external to the protective effect of lubrication grease have been washed.If there are damaged tilt of the hair, will increase the friction between the hair combing hair, lead tangled together, mutual friction and intensify the hair damage.This is not over, anionic surface active agent to remove grease, simply adsorption in the hair.Wet electronegative hair, but also under the action of water affixed together, they can turn a dry completely, because the repulsion from each other can not far away.If with a plastic comb through down point electrostatic, it would be exciting.

Anionic surface active agent to bring the electrostatic problem solved, we in the conditioner to cations have, such as quaternary ammonium salts.But it also could not solve to cuticle damage is the first of a series of hair problem.This can not comb hair will avoid it -- in addition to carding, dyeing hot chemical, thermal and UV rays of the sun, more make hair badly hurt.At this time, oil comes in handy: lubrication to reduce the chance of injury caused when combing hair.From ancient times the girls dresser osmanthus oil until several decades ago placed on the shelves of the conditioner, the protagonist is fat.PDMS's role is capable of attachment in the hair, fill hair damaged hair, so that the surface becomes more smooth, namely advertisement often alluded to "repair" function.After "repair" hair, bright and easy to comb does not say, oneself also more robust.

Without conditioner treated hair cuticle angular, impaired clearly visible; the treated surface is more smooth

PDMS has another advantage: the formation of the protective layer can obviously keep the hair moisture stability -- and simple use of shampoo hair after compared, use hair conditioner hair under low humidity conditions moisture loss is reduced, and high humidity condition and prevent hair from excessive moisture.Hair too wet or dry will cause difficulties, combed hairstyle changes.

Xihu supplies of oil will affect the scalp healthy?

PDMS hair effect is be obvious to people, especially on longer or after perm hair -- such hair, hair cuticle damage more serious.But because of its mode of action is by attached to the hair, to fill the open damaged cuticle, so, some people began to worry that it would be deposited in the scalp, causing the inflamed acne, alopecia, such phenomena.

First of all, cosmetic composition evaluation (CIR) expert panel that it used in cosmetics are safe, not to stimulate the skin of.Although it can be formed on the skin of hydrophobic membrane, but is permeable to gases.In a literature search process,GHD Benefit did not find any of it and pox, induced acne, hair loss, caused by allergic related information, it is often used in mark acne free (not pox) or oil free (oil-free) such products.It is compared with the traditional oil advantage.

That we can retrieve a physician on PDMS may lead to blockage of the pores of the scalp is suspected, but the doctors themselves failed to provide reliable evidence to support his ideas.This is clearly not the mainstream viewpoint -- is still no literature reports PDMS induced pore clogging example.

Most shampoos will add a small amount of PDMS, I hope your hair while cleaning up some hair effect.But in fact, as products such as hair effect is very limited. (run out of hair is very edgy yes or no!), it remains in the scalp to plug the pores of possibility is very low.Because shampoo to add PDMS content rarely (less than 1%), in plays the role of cleaning the surface active agents, together with a large number of water flushing are almost exhausted.And hair conditioner, hair of these contain more oil flushing type conditioning products, are not recommended for the scalp, as long as the painting in the hair and above part good.One can reduce the dosage, two is the root parts of the hair cuticle damage less, do not require the use of these products can be alleviated, three hair greasy and heavy collapse.

In addition, the improved structure of PDMS -- for example into ether or increased amino silicone oil and hair, can make the binding capacity greatly increased, while water soluble increase.This product can effectively attached to the hair, and in the skin and other parts remain less.Has been "silicone plug the pores" notion that friends don't have to worry too much about.

That is, in the shampoo products add PDMS sometimes do have small defects.For example, short people have little hair care needs, if they choose to products containing PDMS, will have to bear the extra cost, some "is not worthwhile".In addition, because PDMS can be absorbed by the hair, causing the hair thicker, weight change, and simultaneously reduces the hair between the electrostatic, then dry hair usually appear flat, no fluffy.For fine hair person this is not a good phenomenon.Such a situation, we still have not containing PDMS shampoo available.

Conclusion: PDMS can remove hair scale, reduce hair damage caused by friction, the timely or long-term benefit is obviously.Contrary to speculation it on the scalp of the harm is not confirmed.If you have a hair care needs, why should it says "not"?Of course, if your hair is short, or does not need so much protection, or just don't like the components of silicone oil,GHD Blue Serenity-NEW can select those not containing PDMS shampoo, hair conditioner -- they contain cetyl stearyl alcohol is, or sunflower oil, composition, and some of them have a tangible induced acne and smallpox.
