Niba ushaka kugera ku ibara ryiza kandi ringana ukoresheje uruhu rukoresha uruhu, kumenya igihe ugomba gusiga ibara ry’uruhu muri buri myitozo ni ingenzi cyane. Abantu benshi bizera ko kuguma mu ruhu rukoresha uruhu igihe kirekire bizatanga umusaruro wihuse, ariko iki ni igitekerezo kidasanzwe. Mu by’ukuri, umusaruro w’uruhu ukoresha uruhu uterwa ahanini no gufata igihe, uruhu ruhoraho, no kwita ku ruhu neza kuruta uko bigenda igihe kirekire.
Iyo ukoresheje agakoresho ko gusiga ibara ry'uruhu, urumuri rwa ultraviolet (UV) rutuma uruhu rwawe rukora melanin, ibara rituma uruhu rwawe rwijima. Ariko, gukora melanin ni inzira y'ibinyabuzima buhoro buhoro. Uruhu rwawe rukomeza kugira ibara ndetse na nyuma y'uko igihe cyo gusiga ibara kirangiye. Kubera iyo mpamvu, kumara igihe kirekire mu gakoresho ko gusiga ibara ry'uruhu kirenze icyo wasabwaga ntabwo bizakwihutisha cyane ibara ry'uruhu rwawe, ahubwo bizongera ibyago byo kwangirika k'uruhu rwawe.
Ku batangira, igihe cyo gukaraba uruhu gisabwa akenshi ni hagati y'iminota 5 na 7 kuri buri myitozo. Iki gihe gito gifasha uruhu rwawe kumenyera buhoro buhoro imirasire y'izuba kandi kikagabanya amahirwe yo gushya. Nyuma y'amasaha make, uruhu rwawe rumaze gutangira kugira ibara ry'uruhu, ushobora kongera buhoro buhoro igihe cyo gukaraba uruhu ho iminota 1-2 kuri buri myitozo, bitewe n'uko uruhu rwawe rubyitwaramo.
Ku bakoresha basanzwe bafite uburambe mu gusiga ibara ry’uruhu, amasomo ashobora kuva ku minota 8 kugeza kuri 12. Abakoresha bakomeye bafite ibara ry’ibanze rigezweho bashobora gusiga ibara ry’uruhu mu gihe cy’iminota 12-15 kuri buri somo. Ariko, ni ngombwa gukurikiza imipaka ntarengwa yo gusiga ibara ry’uruhu isabwa n’uruganda rukora ibara ry’uruhu cyangwa abakozi ba salon.
Kimwe mu bintu by'ingenzi mu kugena igihe cyo gukaraba ni ubwoko bw'uruhu rwawe. Uruhu rwiza rushya byoroshye kandi rugomba gukomeza gukora amasaha magufi hagati yarwo n'igihe kirekire. Uruhu ruringaniye rushobora kwihanganira igihe cyo gukora amasaha maremare, mu gihe uruhu rwijimye rushobora kwihanganira igihe kirekire ariko rukagomba kwirinda kurwara cyane.
Ikindi kintu cyo gutekerezaho ni ubwoko bw'uburiri bwo gusiga ibara ry'uruhu. Amwe mu mabara agezweho yo gusiga ibara ry'uruhu yakozwe neza kandi agakwirakwizwa neza mu buryo bworoheje, bigatuma abayakoresha babona umusaruro mwiza mu gihe gito. Ibi bivuze ko ushobora kudakenera gusiga ibara ry'uruhu igihe cyose utekereza kugira ngo ubone umusaruro ugaragara.
Guhorana ibara ni ingenzi kuruta igihe kirekire. Aho kugerageza kugira ibara ry'uruhu mu gihe kimwe cyangwa bibiri birebire, ni byiza gukurikiza gahunda yo gusiga ibara ry'uruhu hamwe n'igihe gikwiye. Ibi bituma uruhu rwawe rukomeza kwiyubaka buhoro buhoro no kugumana ibara ridafite ibyangiritse bitari ngombwa.
Kwita ku ruhu mbere na nyuma yo kurusiga uruhu bigira ingaruka ku gihe ugomba kumara urushana. Gukuraho ibara mbere yo kujya mu ruhu bifasha gukuraho uturemangingo tw’uruhu twapfuye, bigatuma rurushaho kuba rwiza. Nyuma yo kurusiga uruhu, gusiga ibara ry’uruhu ni ngombwa kugira ngo uruhu rwawe rukomeze kugira amazi meza kandi hirindwe ko uruhu rugabanuka, ibi bishobora gutuma igihe cyo kurusiga uruhu kigabanuka.
Ni ngombwa kandi gutega amatwi uruhu rwawe. Niba ubonye umutuku, ububabare, cyangwa kutamererwa neza nyuma y'imyitozo, bishobora kuba ikimenyetso cy'uko igihe cyawe cyo kwisiga cyari kirekire cyane. Muri ibyo bihe, ugomba kugabanya igihe cyo kwisiga no guha igihe kinini cyo gukira.
Muri make, igihe cyo gukora imyitozo ngororamubiri gikwiranye n’ubwoko bw’uruhu rwawe, uburambe bwawe, n’ibikoresho byawe, ariko muri rusange kimara iminota 5 kugeza kuri 15. Imyitozo migufi kandi ihoraho hamwe n’ubuvuzi bwiza bw’uruhu bizaguha umusaruro mwiza kandi utekanye kuruta igihe kirekire kandi kidakunze kugaragara.
