It'll all be all right. There are many products out there that aren't expensive and work wonders for the hair. And there are places that you can go that sell for cheaper than others. I'm the cheapest person ever when it comes to buying things. Here's some tips that I follow:
1. Try to go to Wholesale Beauty Supply places to get your things. They usually sell for cheaper than Sally's and salons and often times carry the same things.
2. Get rid of the unnecessaries. For instance, I found it unnecessary to waste money on a leave-in conditioner when I can dilute my regular conditioner, put it in a spray bottle, and spray that in my hair. It works just as well and saves me money!
3. Indian Stores-I just discovered this. If you are fortunate enough to have one near your home, they sell oils like Coconut and Amla for a lot cheaper than online, and they are good quality. Also, I bought an herbal cleanser called Aritha there (soapnut powder) and it only cost 2 dollars. And they sell Henna really cheap. I guess you can look in phone books to see if there's any near you.
4. Health Food Supermarkets-I love Whole Foods. I can buy a big 32 ounce bottle of 365 brand conditioner for less than 4 dollars, and it lasts a long time. I also use it as a leave-in so it kills two birds with one stone. I like the fragrance free conditioner because it's simple, not overpowering, and very moisturizing. They also sell a lot of other things that may be useful for cheaper.
5. Wally World!-Walmart also sells a lot of good products for cheap. For instance, they sell organic root stimulator deep conditioning packs for cheaper than convenience stores. Also ORS deep conditioning packs are a good alternative to expensive deep conditioners. They only cost around $1.20 a pack, and I can sometimes make that pack stretch to two servings!
6. Dilute it or spread it thin-I love doing this. A lot of times I can be guilty of using too much product unnecessarily, and this wastes money!Now, when I Deep Condition my hair I try to use just enough to lightly coat my hair. It's going to seep into the hair anyway, so piling a lot of product on defeats the purpose. And also, If I see that my conditioner is running low, I dilute it with water. That makes it last until I can go out and buy some more of it.
All and all, those are just a few suggestions I came up with. I hope they helped! But there are always ways of getting the products you like for cheaper or finding products that are just as good but cost a lot less.
