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.
