I wish I could (conclusively) help you because I can tell you things but as this is the internet, you are always going to get conflicting information. I can tell you some things I know as an herbalist however...Also, I am currently going through a protein-overload on top of my hair and am TRYING not to become too paranoid about what is in my products in relation to proteins.
I have to agree with, "Firefox" based on what I know. Do you know even fruits have protein? Not just avocados, but everything from an apple to a cherry, to a grape has trace amounts. It is pretty impossible to avoid a product without even trace amounts of protein.
For myself, I am simply trying to steer clear of anything containing outright protein and actual coconut oil (since SOME say it can act like a protein and can help the skin and the hair to retain it as well) as well as jojoba oil (since my hair does not like it so much anymore though I did use it on dry hair which may have been why it dried out my tresses at that time), and panthenol (since, again, SOME say it can behave like a protein and cause a negative build-up on the scalp and strands).
As for grasses...Yes, they can be high in proteins...I take barley grass daily and two teaspoons of the dried powder contain 1 gm. of protein. But I would not worry about this so much as in how many grain grasses do you see in hair care products? Green drinks and health shakes maybe!
Herbs...Well, yes, certain botanicals like comfrey root, aloe vera and seaweeds contain proteins which is why, in part, they are so mucilangous. Again, how much protein ends up in the finished product, remains to be seen. During the extraction process, only so much is going to be retained. Plus add that extract to a big vat of other ingredients, take into account oxidation before bottling and more oxidation upon opening that bottle and more as it sits open on your shelf, and we are likely talking trace residual amounts of proteins from these herbal extracts.
I really would not worry about the hops, sweetheart. I am obsessing
about ingredients and the current state of my hair but I am also trying to think rationally on top of that.
A seemingly unrelated example
When I was pregnant, I had friends flipping out about eating everything from apples, to celery, to basil (so much for all those big Italian families such as my own, eh?
) because of some misinformation they read online. It was ludicrous. I took both red raspberry leaf and flaxseed oil daily during my pregnancy despite newly-touted pish-posh that they can cause miscarriages. My herbal knowledge understood differently. I gave birth to a perfectly healthy little boy who was overdue by 13 days! There is no better herbal for a pregnant woman than red raspberry leaf. It prevents miscarriages, speeds up labor by helping the cervix to dilate and by toning the uterus (I only had 10 minutes
of pushing!) and for all of my love of herbs, it saddens me that this sweet and precious little plant has received such a bad reputation. Plus the berries and leaf tea are 'delish'
So while this little tale may seem unrelated, it is actually an example of how there is simply too much info available to us nowadays. A lot of it is completely WRONG. One person writes one thing and then it spreads like wildfire. It's crazy!
Stay cool and peace.
