Hey there ranran!
I had the worst
hair in SE Asia including KL, one of the things that pushed me to research and find the CG method.
The BodyShop makes some CG products (the Rainforest line). Some people have had good luck with the Cottonseed Curl Cream. Otherwise I'm not aware of any CG-friendly products on the ground.
If you ever make a trip down to Singapore I can point you to a store called "Brown Rice Paradise" in Tanglin mall which has the biggest selection of CG products (though marked up). Also SASA has Giovanni products... I think there is also SASA in Malaysia?
If you can order online, one of your best options iherb.com. They have good prices and will ship to Asia. There are also discount codes (look in my siggy). Curlmart also ships internationally, but their shipping prices are outrageous.
Don't bother with any of the L'Oreal "curl" stuff... it's a waste of money IMO.
The best way to control frizz is to choose products that are suited to your hair properties. Here you can read more about your hair properties: Curly Hair Basics | Live Curly Live Free
These are some things I would advise you to do:
1. Ditch the drying sulfate-shampoos. These dry out your hair and make it frizzier. You can look into cowashing or a sulfate-free low-poo. iherb.com has a few low-poos try the Nature's Gate Chamomile or the BROO shampoos. (Don't go for the Body Shop shampoos... too drying IME). Note: if you're going the cowashing route you must not use any products with silicones!
2. Get a good rinse-out conditioner suitable to your properties. If you have fine hair, you should get a rinse-out conditioner with protein. If you have coarse hair, go for a rinse-out conditioner without protein. If you have damaged hair however (from dying, heat styling etc.) some protein should be a good. I do actually like the Body Shop conditioners and iherb.com has many conditioners to choose from.
3. (optional) Get a nice leave-in conditioner. Could be the same as your rinse-out conditioner, but you may want to stay way from glycerin- or aloe- based conditioners (so not the NG ones). This may or may not have protein, depending on your hair's needs.
4. Gel. I would highly recommend making your own flaxseed (linseed) gel. It is light and works like a charm. It's also super cheap!
5. Don't touch while drying and look around the board for techniques.
6. DO NOT GO TO A HAIRSTYLIST THAT USES THINNING SHEARS OR RAZORS ON YOUR HEAD. If curly hair care knowledge is low in the US or in Europe it's extra-extra-low in Asia from my experience. It's very likely that a stylist will cut your hair the way they're supposed to cut straight hair... and may be quick to use thinning shears or razors. Just say no thank you and ask to use the regular scissors. You can always take this with you and ask for these things: What Should I Tell My Stylist?
You could also try cutting your own hair... this will be my next project!
Basically I just want to tell you that I went from having utterly awful frizzy to actually being able to manage it after I discovered nc.com... in the tropics. So if I can do it you can do it too! ::hugs:: and go forth in the humidity!
