    This study aims to analyse the components of the hairdryer to 1ecogniz the quantities or improvements in the features of the components involved, and it is necessary to study possible sustainable design improvements. Thus, it is implementing Design for Manufacturing (DFMA) and Life Cycle Analysis (LCA) approach to assist sustainability analysis. The results from a product survey of consumers found that 75% of consumers are from women while the rest are men who use hair dryers. Therefore, people in the 18-30 years old prefer to use the hairdryer when while 18.8% of users often keep the hair dryer on the makeup table and 12.5% of users keep the makeup drawer to look neat. While the results of sustainability study on hair dryer products have found that before analysis using PP Copolymer material there was a good impact on the product analysis in terms of Material Unit Cost of 2.80 USD / kg compared to previous use of ABS material of 2.90 USD / kg. While in terms of Material Financial Impact from the use of PP Copolymer there was a decrease of 0.20 USD compared to material abs usage of 1752.00 USD. In terms of weight the hairdryer has also experienced a weight reduction of 70.05 g to 60.04 g. But in terms of duration of use still the same period of the application for a year and also in term transportation still remain the same as truck distance 1600 km. The surface area of the product also decreased from 76268.30 mm2 to 74199.49 mm2. The methods used for hair dryer production are finite element analysis and sustainability analysis..
