I've always been curious about Kerastase products, this thread might just have persuaded me to give them a try!
It's not a hair oil but I love Aveda's nutriplenish leave-in conditioner, it doesn't seem to weigh my hair down but does give some TLC to frazzled ends.
Very little drops of organic Argan oil purchased from Amazon. I color / have highlights on my hair, and so far no split ends! If you use too much, then you’ll get that greasy strands look - I over applied the first time. 😂
Only a less than a dime size depending on the length of the hair and glide from mid-length to ends (def avoid the roots).
I heard organic rosemary oil is a great mask to use an hour or two before showering to promote hair growth for the scalp or roots. I haven’t tried that yet, but some ladies swear by it.
If you are styling your hair, kerastase elixir ultime works best. No fly aways and no greasy look, but I don’t know if it is drying. I use it once in a while.
My hair is quite fine and I need to be careful because too much product can weigh it down. I get good results from Kerastasse Densifique. I use the shampoo and conditioner. It would be too much product on my hair to add anything else.
