The curly hair that has been permed for nearly two months is almost straight! !

1. Refractory hair: First, wash your hair, blow dry it, apply the first dose (softener), and heat it with a plastic cover in an oil roaster 15-30 minutes, sometimes it takes about 60-70 minutes. It is best to use an electric heating cap to heat it, because intractable hair is sometimes difficult to soften or sometimes related to liquid medicine. Rinse it with water after softening, blow it with a hair dryer until it is 90% or completely dry, put in a SPA (water bath perm) and a digital perm core, plug in the power supply (adjust the temperature on healthy hair) for 20-30 minutes, unplug the power supply, (after winding the core before heating, put a thick paper towel on it and add a clip to prevent the clip from clamping the hair), and then let the hair cool. Spray the second dose (styling agent) evenly with a watering can once every 8 minutes, once every two or three times, then take out the hair core and leave it for 5 minutes to eliminate the elastic indentation of the hair root. Then rinse, dry the towel and blow it to 50% to 70% dry, then apply it on the perm without washing the care agent.

2. Normal hair quality: wash your hair, blow dry it, apply the first dose (softener), heat it with a plastic cover with an oil generator, preferably with an electric cover 15~20 minutes or 30 ~ 40 minutes, rinse it after softening, blow dry it with a hair dryer for 80% to 90%, and then go to the SPA (water bath perm) and digital perm. When the time comes to cool, spray the second dose (setting agent) evenly with a watering can once every 8 minutes, once every two or three times, and then take out the core and park it for 5 minutes to eliminate the elastic indentation of the hair roots. Then rinse, dry the towel and blow it to 50% to 70% dry, then apply it on the perm without washing the care agent.

3. Slightly or moderately damaged hair: firstly, wash the hair, dry it with a towel, blow it to 50% dryness, then apply the first dose (softener), heat it with a baking machine with a plastic cap, preferably with a charged cap 10- 15 minutes, rinse it after the softening test is successful, and blow it to 40% to 50% dryness with LPP or PPT nursing agent. When the time comes to cool, spray the second dose (setting agent) evenly with a watering can once every 8 minutes, once every two or three times, and then take out the core and park it for 5 minutes to eliminate the elastic indentation of the hair roots. Then rinse, dry the towel and blow it to 50% to 70% dry, then apply it on the perm without washing the care agent.

4. Seriously damaged hair: first wash your hair, dry the towel, evenly apply PPT or LPP care agent, then apply the first agent (softener), stay for 5~ 10 minute, rinse after the softening test is successful, dry the towel, apply PPT or LPP, remove the SPA (water bath perm) and digital perm core, and (adjust the heating temperature of damaged hair) for a fixed time of 650 minutes. When the time comes to cool, spray the second dose (setting agent) evenly with a watering can once every 8 minutes, once every two or three times, and then take out the core and park it for 5 minutes to eliminate the elastic indentation of the hair roots. Then rinse, dry the towel and blow it to 50% to 70% dry, then apply it on the perm without washing the care agent.

Second, matters needing attention:

1. Softening degree test: Pick out three or four hairs and wipe off the softener.

2. Take it out around your finger for 2-3 times. Put it in the palm of your hand, and it will soften in its place instead of bouncing off. Or take 1-2 hairs for stretching. If you let go easily, the scalp will soften in place and you won't feel pain.

3, the number of hair cores: generally around 7- 14, there are not many hair cores, too many flowers are small and old-fashioned.

SPA (water bath ironing) and digital ironing are different in principle from cold ironing. This is a thermoplastic ironing. After applying 1 dose, chemical reactions began to occur inside the hair, molecules between keratin were softened, and chemical bonds were broken and rearranged. The internal heating of different types of SPA digital curling mandrels generates infrared rays, which promotes the change of molecular structure between keratin and produces new shapes. With the increase of the core temperature of SPA and digital perm and the heating of the external clamp, the keratin structure is hardened and fixed again under the physical action. This is the chemical function and physical function of SPA (water bath ironing) and digital ironing.

Fourth, the hair after perm is loose and hairy, and the elasticity is not enough.

It may be the loose hair caused by the poor connection of the weight of the upper and lower layers of hair during the trimming before perm. There is too much hair in the upper layer and too little hair in the lower layer, and the hair ends lack a sense of weight. After softening and washing, before finishing the hair core, a small amount of LPP or PPT nursing agent should be applied to the softened part of the hair for heat protection, which can prevent the hair from being hairy and inelastic.
