Do not buy
Very very disappointed. It makes my hair so greasy . After one week use I found my scalp get itchy and so sensitive , doesn’t do anything about making hair grow . Be careful when purchasing because they won’t let you return or request a refund. I spent $76 dollars for nothing but problems. Never disappointed like this about L’Oréal product and 鶹 service

    3.0 out of 5 stars Not an oil..but a quality Loreal product.
    Reviewed in Canada on December 11, 2024
    Verified Purchase
    I am not sure why they describe this as a serum oil - it is not an oil in any way. It is a light, liquid hair spray serum. I don't notice any significant benefit to using it at all. But, it is a nice Loreal product, lovely scent and very conditioning / softening to the hair. I don't think it has any hair thickening, regrowth or hair repair properties at all that I can notice. I am not surprised or too disappointed in the product - it is as expected. You can't get DNA miracles out of a bottle.
