Strengthening Conditioner Patrice Beaute Clean Strenght Conditioner

Usually, the products that work for me (colored hair) don't work for my sister (non-colored hair) and vice versa. This product didn't work for either of us.
We have thick, porous hair, "maybe it's meant for fine hair," I thought, but I see a girl in the comments below who wasn't impressed either...
I also tried combining it with other products, didn't give up hope, but no, all in vain. The hair becomes unrealistically dry, unpleasant, almost like oak. And it doesn't "strengthen" anything.
I do not recommend wasting money on this useless product.

I want to start by saying that I did not purchase this product here, but I still wanted to leave a review. About my hair: blonde, thin, and brittle. Well, this conditioner turns my hair into one solid, tangled mess. I have tried it around 4-5 times in different combinations (with sulfate and sulfate-free shampoos, various masks and leave-in treatments), and the result is always the same - dry, tangled hair that breaks much more easily than before. I had to cut about 7 centimeters off because there was practically nothing left - just broken strands that are impossible to comb through. Another thing I didn't like is that when my hair dries, it becomes sticky, but this goes away after it is completely dry. Conclusion: definitely NO!
