There are currently three types of eco-friendly products: the old white eco-friendly 140ml, the new green eco-friendly 150ml, and the large eco-friendly 228ml. The three types of functions are different. The new green eco-friendly 150ml is an improved version of the old model, which has enhanced the durability after dyeing and is safer and healthier. The large eco-friendly is based on the ordinary eco-friendly, with the additional effect of preventing hair loss and promoting hair growth.
Old Ecology 140ml, originally white box, really gentle, now green box, really gentle.
New Ecology 150ml, originally in green box, Jie Wenhe, now in green box, more gentle.
The original white box version of the Eco-System 228ml is truly gentle, and the new green box version is even gentler.

In June 2022, in accordance with the Advertising Law, the word 'gentle' is no longer used. All eco-friendly products will be changed to 'cozier'. The 140-piece set is now 'cozier', and the 150-piece set is also 'cozier'. The 228-piece set is also 'cozier'.
