Several of you asked about how I make my own conditioner. I use base products from a popular German DIY-cosmetics shop called Hobbythek. They sell the ingredients and have books with recipes. Here is the one I use:
There is a conditioner base, and to that you add extras depending on the hair type.
Haarguar HT (Hydroxypropyl Guar, Hydroxypropyldrimonium Chloride)
Haarsoft (Coco Glycoside and Glyceryl Oleate)
Cetyl Alcohol (I skip this now)
Now, to this base you add the fancy stuff. It goes like this:
Normal hair: plant-based oil, silk protein, D-panthenol
Fine, thin hair: plant oil, silk protein, D-panthenol, Vithaar (= Aqua, Hydrolyzed Wheat Protein, Oryza Sativa Extract, Phenethyl Alcohol, Proline, Alanine, Serine, Citric Acid, Biotin )
Dry, split hair: plant oil, Nuratin P (= Hydrolyzed Wheat Protein, Hydrolyzed Wheat Gluten), silk protein, Elastinpulver P (= Hydrolyzed Wheat Protein), D-Panthenol
Very dry, or negroidal hair: plant oil, Fluidlecithin CM (= Glycine Soja, Lecithin, Tocopherol), silk protein, D-Panthenol
Since I skip the fatty phase, all I have to do is mix the ingredients together and pour into a container. I'm pretty satisfied with the conditioner, apart from the fact that the last batch I made was a bit sticky. So far I have been too lazy to examine the ingredients and find the guilty one.
I think that each make-your-own-cosmetics store carries different ingredients and shares its own recipes based on those ingredients. This means it might be hard to get the exact match to the above ingredients in your local DIY-cosmetics store (which probably has its own recipes which might be equally good or better).
On that note, care to share names of make-you-own-cosmetic stores that you have had a good experience with?
