How long does thermal reconditioning last




















Your only option is to grow it out and cut off the treated sections. To ease and smooth the growing out process and help with frizz and time with your hair dryer , Abramite recommends —you guessed it—a keratin treatment.

Although Japanese hair straightening lasts forever, that doesn't mean it's a one-and-done process. Since your hair will still continue to grow, you'll need to touch it up after eight to ten months, or whenever you have four inches of new growth which is the length needed for a proper product application and flat-ironing.

To that end, Abramite explains that Japanese thermal straightening is best suited for wavy and curly hair patterns that are looser at the scalp, which allows for texture continuity between the treated hair and regrowth. Please do!

Abramite says the best way to prepare your hair for Japanese thermal straightening is to arrive with clean and air-dried hair in its natural texture. The process takes around four hours from start to finish, so arriving with prepped hair will reduce your time spent in the chair.

For 72 hours after treatment, you've gotta wear your hair straight and down in all its glory and, just like a hair perm , keep it dry. Not only that, but your hair also needs to be kept free of tension or pressure caused by bobby pins , elastics, headbands , or anything else that could crease it. Abramite explains that during this delicate time, your hair is neutralizing and tension can leave an indentation behind for good.

A fair amount of debate circulates around keratin. Keratin straightening treatment takes much longer though. And for all that time, your hair will only remain straight for 3 weeks. Another big difference is the use of formaldehyde-based cream in keratin straightening. You may have heard of formaldehyde. Your move. There are many different varieties of hair relaxers. Retailers sell a bunch of different chemical mixtures as relaxers.

But most are alkali-based, with sodium or calcium hydroxide among the most common base ingredients. These are harsher on your hair than the cystine and ammonium thioglycolate solutions that play a role in Japanese straightening.

Relaxers strip an entire layer from the structure of your hair, where thermal reconditioning only breaks the bonds between layers. This is a pretty huge difference. Relaxers are cheaper, certainly. However, their effects also only last for about 6—8 weeks. If you only want a short-term commitment to straight hair like if you have a wedding or prom coming up , then having your curls relaxed may be your preferred choice.

Any additional chemicals will only add to the damage, so you have to be prepared for the commitment to let it grow out. Hair texture plays a big role in the success of the treatment, particularly for African American women. Depending on your hair, you might be better off with chemical relaxers. Before you schedule an appointment for the treatment, consider booking a consultation first. It's important to fully understand the risks involved and to determine if you're a good candidate.

You can get Japanese hair straightening treatments anywhere in the country, but your best bets are in larger cities. In New York City, for example, the treatment is mainly offered in the trendy salons sprinkled throughout downtown, with some in Brooklyn and Queens. For these places, the damage that it inflicted on women's hair wasn't worth it. Because there is some risk of damage involved, it's best to pick a salon and stylist based on experience rather than price.
