I love DIY, do I need bottled products?

So when I began my hair journey, I tried almost all the DIYs but what I found out was that these were breaking my hair especially when it came to the raw eggs, mayonnaise etc. DIY isn't bad but you should know that doing a DIY protein doesn't really do anything to your hair because the protein bonds in these ingredients are big such that your hair can't absorb them.

Well manufactured bottled protein like the Sheabeutimia Protein Treatment Mask for example has active ingredients that have been broken down into amino acids that the hair easily absorbs and thus very good to repair and make the hair strong.
