This reason is well simple to explain:
If a client come in the hairdressing parlour with a determined capillary anomaly and the hairdresser, for lack of preparation or formation, he is not capable of detecting it and to treat it, he runs the risk that this client respond to another similar establishment al our in which they carry out where not alone and capillary processing they settle him the problem but besides he like the deal that receives and the service in General, not being worthy the difference of price. For certain would be finished losing the client.
