Hi
@lady1979. My hair tends to stay very dry and brittle so I find the mask to be worth it. I haven't tried any other products to say if they are worth it or not. My hair needs extra help and so far this leaves my hair soft after I rinse which doesn't necessarily happen when I use other deep conditioners. It is also very concentrated so I don't use as much as other products. I bought the jar in April and it will probably last me until next April. I only use the mask once every 4 to 6 weeks.
Not a lot of things work for my hair so I've been willing to try things that are a little more expensive. For my hair the mask work well enough that I'm willing to try other products in the line. I only have the Resistance shampoo and mask and the Nutritive MasqueIntense in my stash. I plan on trying a cowash, an oil and a regular conditioner to compare them.
Most of my hair stash is made up of the Mane Choice and TGIN products which aren't that expensive. I use the Kerastase when I plan to do something damaging to my hair like blow drying/flat ironing which I only do 2 or 3 times a year so the products will last me a while.
If you find cheaper things you love stay with those. My hair just seems to like expensive things.
