L'Oreal Owns the majority of hair product companies..they are the mother company.
They are reaping the rewards on both sides of the fence.
Which makes me just cringe at times.
.The general public gets confused ( as L'Oreal wants them too) as to what is professional and what is for OTC..This is one reason I refuse to use anything that has the l'Oreal label on it in the salon.
L'Oreal owns most everything! We are an exclusive Series Expeire School, we are in fact, the only SCHOOL that is registered as such, what this means is we have acess to the Professional ONLY products that are produced by L'oreal, in exchange for this we do marketing and research for them. We keep track of what the trends are, client services, colors etc and report them to L'oreal. Funny thing about this is that every so often they will send us a sample package for the students to use and it isn't always Lo'oreal that's in the box.
L'oreal owns Artec and Redken, Redken purchased Clairol awhile ago and before that Clairol bought Matrix and Wella. So, who owns what, good luck following that path!!
The major companies realise this industry is worth billions each year and don't want to lose any of the market. They must research and test products before they reach the consumer, whether it is a professional consumer or an over the counter product, so when they have developed a product, if it does not meet industry standards for a professional product it is sent to another area of the manufacturing plant where a new scent, different color and fillers are added, generally water, methylparaben (great preservative all hair products have traces of this to allow stable shelf lives) which can coat the hair strand in large quantities, and a lathering agent- we relate clean to bubbles.
All shampoos do what they are designed to do, clean the hair. Are some shampoos better, YES it depends on the needs of your hair and the chemical treatments or styling alternatives you use.
Cost issue- most professional salon shampoos are concentrated, you should use 1/4 to 1/8 the amount you were using of an over the counter shampoo. Realistically this means that you got 4X the shampoo for usually twice as much, which one is less expensive? I really stink at math, so I'll let you figure that one!
Kids- little heads, less shampoo. If they are of an age that they are shampooing themselves and use too much, dilute it, save a bottle and add a little of your own water, yes it will be runnier but you haven't added wax to thicken it so that is to be expected.
I could go on and on about the differences, I've been lucky enough to go and tour some of the manufacturing sites and talk with chemists of various companies. The differences are there, it just takes time, effort and continuing education to recognise them.
