Hello bubble hair color - amonia free

Hello po, 8 weeks preggy here.. nagbabasa po ako ng articles sa google kung anong pwede hair color.. may nabasa po akong pwede naman basta AMONIA FREE daw.. And then ndiscover ko tong Hello bubble from korea..hindi sya yung paste like other hair dye.. bubbles lang po talaga sya tapos apply sa hair no foul smell. Sino po naka try dito gumamit ng hello bubble while preggy? 😊
