Looking back at the ingredients list:
Ovation:Deionized Water, Stearalkonium Chloride, Glyceryl Stearate, Cetearyl Alcohol, PEG-40 Castor Oil, Cetrimonium Chloride, Hydrolyzed Keratin, Panthenol, Tocopheryl Acetate, DM DM Hydantoin, Methlparaben, Propylparaben, Tetrasodium EDTA, Frangrance
Mega-Tek Rebuilder:Deionized water, hydrolyzed keratin protein (HU), stearalkonium chloride, glyceryl stearate, peg 100 stearate (DI), marine protein (DI), peg 40 (no castor oil), panthenol, dimethicone copolyol (the one cone), magnesium citrate (DI), allantoin (DI), amino acids (DI), methylparaben, mucopolysaccharides (DI), polyparaben, imidazolidinyl urea (DI), fragrance
DI = Different ingredient AND HU = Higher up on the list
To counter act the dryness potential... I am going to mix a little conditioner / aloe gel and sweet almond oil in to my Mega-tek. The way I see it, the OCT just has more moisture based conditioners high up in the list vs the MT. I may use some of the Hemp Seed Oil which is high in omega oils. This totally make sense to me.. I actually prefer to put my own moisture into the mix because I'll choose good ingredients.
I am going to shampoo with ORS Aloe just to get rid of any product build up I might have before using the MT mix.
ETA: I'll put the straight MT on my scalp between washes...
ETAA:Allantoin - is a healing, moisturizing, soothing and anti-irritating, keratolytic and non-toxic agent useful in dermatological, cosmetic and veterinary preparation. Allantoin is a valuable cell-proliferating healing agent which stimulates healthy tissue formation. Allantoin has a pronounced keratolytic and skin softening action, acts as chemical debrider of necrotic and scaling tissue, cleasing up the areas where applied. Allantoin is effective at quite low concentrations, 0.1% up to 2%.
As natural component, Allantoin was found in fetal Allantoic fluid, in wheat germ, rice polishings, confrey roots, in dog urine and in the urine of pregnant women, in the earth-worm and as organic component of many soils.
