You must assist the salon repair of your hair with the correct aftercare. If we do a Terre a Plex Straightening or Repair and you go home and disrupt the acid and pH balance of the hair that we are attempting to repair with non recommended products you may revert the progress you made which could be wasted time and resources.

They key is to use the correct aftercare. It is not to just a ruse to get you to use our products but it is simply to ensure that we are doing our best to make your hair healthy again. We want to ensure and help your hair recover from the damage caused and to keep the straightening affect the longest possible.

When you do intense damage through a chemical service such as bleach, colouring or chemical straightening you break the covalent/disulphide bonds within your hair.
Conditioners, oils and masks are only topical staying on the outside and temporarily making it look healthier.
Plex repair fixes your molecular broken bonds which is the root cause, which causes unhealthy and broken hai. The Plex repair transforms the bonds into hair that has a healthy core and stronger core which results in healthier looking and feeling hair.
