are man made silicones cheaper and do they build up on the hair compared to natural silicones?
it is not possible to obtain natural silicone materials. all silicones are chemically manufactured. in regards to build up on hair, one has to be very careful how one formulates a product and it also depends on the type of silicones one selects to use. some silicones can build up on hair but this is generally a sign of a poorly formulated product. when products are formulated one tries to balance the ingredients in the formulation to optimise the properties one wants from the finished product. at the end of the day it is a balancing act and in the long term the overall product performance is what makes a product succeed in the marketplace.

hair can’t tell the difference between brands or build-up tolerance to any product. your favorite shampoo will work the same every time you lather up, week after week, month after month. if you have very oily hair or favour a particularly sticky styling product that contains wax, it does pay to use a clarifying shampoo once every two weeks to wash away residue.

is there such a thing as a breathable silicone?
silicone technology is very advanced and a wide range of materials are available from light volatile silicone oils to industrial silicone greases. the silicones used in hair care are definitely the light more volatile types that add superior shine and lustre as well acting as conditioning agents preventing fly away hair and acting as anti static agents. these silicones are easily removed from the hair by normal shampooing and in most applications to hair care will not build up. in shampoos and conditioners, silicones aid wet combing, reduce static and increase manageability. they heighten lustre, sheen, and colour definition, without sticky build-up. they are essentially odourless, non-toxic and non-irritating. they leave the hair soft and shiny, looking healthy and natural.

is alcohol bad for the hair – does it dry it out?
alcohol is generally used in hair care to give a product good drying characteristics e.g. a pump hairspray based on alcohol will dry much faster than one based on water. this is where the misconception comes in that alcohol is drying so it must be bad for the skin or hair. if you think about it logically all that happens is that the alcohol evaporates off because it is volatile (lower boiling point than water). as it evaporates it leaves behind any material dissolved in it e.g. hair fixative resin in the case of a hairspray as well as any other conditioning materials that may be incorporated in the product. think about what happens when you boil a solution of salt water - the water evaporates leaving the salt behind. putting it simply alcohol is generally used as a carrier and would not have a drying effect on hair. when products are formulated one tries to balance the ingredients in the formulation to optimise the properties one wants from the finished product. in the case of so called ‘colour safe’ shampoos that protect and lock in hair colour it is a matter of formulating with lower surfactant levels, so that the shampoo is not as aggressive on the hair, and high levels of proteins, film formers, moisturizers, humectants and sunscreen to protect the hair from environmental damage. for ‘colour safe’ conditioners again it is a matter of formulating with high levels of proteins, film formers, moisturizers, humectants and sunscreen and also balancing the ph so as to close the hair cuticle.

what are humectants and why are they used?
humectants are materials that attract water from the atmosphere thus supplementing the moisture content of the hair or skin. this improves the moisturising ability of the formulation. common materials with humectant properties are glycerin, sorbitol, sodium lactate and propylene glycol. these materials attract moisture to the skin or hair.

what do claims like ‘curl memory technology’ mean?
ingredients don’t have memories. it is simply the use of film forming agents and proteins to help curls hold their shape. environmental conditions cause curls to fray, flatten, loosen but when you wash and condition your hair the film forming agents and proteins help curls reform their shape. products formulated for curly hair are lighter so that they don’t weigh the hair down, this means that lower levels of conditioners, moisturizers are used.

what do claims like ‘scan repair technology’ mean?
product companies would like you to think that proteins have little brains and that they scan the length of the hair shaft looking where to repair it – unfortunately the process is more akin to putty being spread on a surface to fill in the cracks. this means as you spread the product across your hair protein will penetrate the hair where it is damaged.
