Until I stopped colouring my hair last year, I would do deep conditioning treatments using my normal conditioner and olive oil mixed together on a 1:1 ratio prior to toddling off to the hairdressers.
Just in relation to some of the other bits and pieces that have made it into the thread…(sorry couldn’t help myself…lol)
Some people find coconut oil fantastic for their hair as it is great at holding protein in the hair. Your hair naturally loses protein (this varies from person to person) so it can mimic a bonding agent. Keratins, and other ‘repairing’ treatments/shampoos etc replace the naturally lost protein - people can become ‘over proteined’ as well (feels like straw).
Olaplex is a different animal again and is a ‘bonding’ agent. This is the explanation they give on their website:
Olaplex works by finding single sulfur hydrogen bonds and cross linking them back together to form disulfide bonds before, during and after services. Disulfide bonds are broken via chemical, thermal, and mechanical processes.
The Sciencey Hair Blog has great information - she is a chemist and really knows her stuff. If you’re like me and want to know the ‘how’ of your hair products work and why - you can’t go past this blog.
