Yep Allen...same in Italy....same everywhere I guess
Allen, as said I think eggs in nurishing shampoo were used everywhere in those years, I found out that in italy till the early 70s as well then anymore....they were more common in 50s and 60s you know I think in "lack" of "chemical-lab obtained" or "syntethized" nurishing ingredients.......
I've read that some people use to make pure egg wraps on their hair.....not everyone would though ....but actually eggs are real effective for hairs and this was known since always, I guess shampoo makers preferred to find alternative solutions that were thought working better than eggs.....actually eggs are still considered from some a very effective way for good hair here explained the eggs wraps some people do, not everyone would drop a yolk on his head though, LOL.
I think shampoos with eggs components like in the past should be reconsidered, cheap to make but valued and amazing at work! As for the many things that today's world has eliminate and or changed to "worse" shampoos with eggs would be one.....this is my thought....
