If you mean OREOR® Creme Developer and other brands the main difference is the name on the bottle. For the most part the ONLY difference between developers is what strength (Volume) the developer is. Standard developer is 20 Vol. (6% peroxide) they have Extra Lift 30 Vol. (9% Peroxide) High Lift 40 Vol. (12% Peroxide) And Low Lift 10 Vol. (3% peroxide) and No Lift 5 Vol. (1.5% peroxide) and each is used for a different purpose - Gray coverage, high lift tints, bleaching, streaking/highlighting, tint backs, semi permanent colors and toning. And as long as the correct Volume is used they are interchangeable. That being said: Dedicated Developers are recommended because they have the correct consistency (thickness) special conditioners and or buffers and correct pH for the product being used. All of which can improve or enhance the product performance. For example: most Creme Haircolors DO NOT have a thickening agent in them like most liquid or gel colors so, if you use a developer that is too thin or liquid it will make the product runny. Also, if your color requires a certain pH to give the proper result using any other developer may result in less than ideal hair condition or may cause premature fading. Hope This Helps. Good-Luck!!
Other than being the primary supplier of the Russian air force for fighters and using the same weapons there is no difference. Sukhoi fighters are much larger and more maneuverable while Migs are cheaper. Though in this case you DO get what you paid for.

The difference between "pop psychology" and scientific psychology is very opinionated. Formally trained psychologists that "pop" is different to "POPULAR"; so cheaper or self-help, or group-work treatment usually means a loss of income, etc. for most professional psychologists. In some psychological approaches, psychologists use the scientifically statistical methods to investigate thoughts, feelings and behaviors. Most "pop" psychology yet has to be completed in these statistical methods. For example, psychologists used to not care about feelings. However the PLACEBO EFFECT is a statistically proven psychological and medical treatment therapy, as every good parent knows. Most professional psychologists will deny that unproven, unresearched and poorly recognized treatments are worthy. Many of these "psychologies" MAY one day become part of respectable, traditional psychology. REFERENCES: "PSYCHOLOGY TODAY" magazine.

Most OTC earwax removal kits are 6.5% Carbamide Peroxide, a little weaker than that specifically for mouth sores, but much cheaper as well. And based on the fact that they get diluted pretty quickly, the difference between 6..5% and 10% is no that much
