I have shoulder-length straight fine hair that suffers from frizz if I let it dry naturally (worse due to living in high limescale area). For years I have used Kerastase’s oleo-relax hair oil just before blow drying it. A bottle last a long time and this product has worked well for me. I’ve now run out of it and they seem to have discontinued this product. Seems to have been reformulated into refillable glass bottle version which gets a bad review. Looking for recommendations please - bonus points for anything that might help to thicken my hair which is starting to feel thinner due to menopause. Happy to spend on this product as I use such small amounts it usually goes a long way.
