– Polymer mai sassauƙa wanda ke kare gashi daga gogayya da zafi.
An ƙera sabuwar fasahar polymer ɗin don ta kasance mai ɗan mannewa kuma mai sauƙin wankewa, wanda hakan ya sa ta dace da masu amfani da ke son gashi mai laushi wanda har yanzu yana da kariya.
5. Fasahar lipid: ceramides, cholesterol mimetics, da madadin silicone
Layin lipid da ke cikin cuticle yana taka muhimmiyar rawa wajen kiyaye danshi da sheƙi. Lalacewar sinadarai na iya lalata waɗannan lipids na halitta. Saboda haka, fasahar lipid ita ce ginshiƙin ƙirƙirar sabbin abubuwan da ke ciyar da abinci mai gina jiki:
– Ceramides da ceramide complexes suna taimakawa wajen gyara “siminti” tsakanin ƙwayoyin cuticle, don haka gashi yana jin laushi kuma ba ya haɗuwa sosai.
– An ƙirƙiro magungunan rage kiba (sinadaran da ke kwaikwayon aikin lipids na halitta) don inganta daidaito da tsarin gashi.
– Ana ƙara amfani da madadin silicone, kamar su light esters, zaɓaɓɓun mai, ko polymers waɗanda ke ba da tasirin zamiya ba tare da tarin abubuwa masu yawa ba. Duk da cewa silicone har yanzu yana da tasiri kuma mai aminci don amfani, wasu masu amfani sun fi son zaɓuɓɓukan da suka fi sauƙin tsaftacewa ko kuma waɗanda ake ɗauka a matsayin "masu sauƙi."
Mabuɗin fasahar zamani ta lipids shine a dawo da jin daɗin "lafiyayyen gashi" ba tare da rage shi ba - musamman akan gashi mai laushi ko mai.
6. Magungunan rigakafi, magungunan rigakafi, da kuma mai da hankali kan lafiyar fatar kai
Na'urorin sanyaya gashi sun fi mai da hankali ne kawai kan gashin da aka yi amfani da shi. Yanzu, sabbin kirkire-kirkire da yawa sun fahimci cewa fatar kai ita ce "ƙasa" da gashi ke tsirowa daga ciki. Shi ya sa na'urorin sanyaya gashi waɗanda suke da aminci a kan fatar kai ko kuma suke da'awar daidaita ƙwayoyin cuta suka bayyana.
