All my mum wants for Christmas is ‘moisture’ (in her hair). She is 70+ with short hair and cannot afford anything pricey so I would love to get her something that will actually do the job. Olaplex is marketed mainly for damaged hair from heat and dyes (mum doesn’t dye her hair at all but always blow dries), but I’m wondering if anyone knows if it’s helpful for ageing hair or just naturally very dry hair?
