I've got short (shaved sides, long on top), thick, heavy hair and have been testing loads of products for about 3 years. Now I have finally figured out which products work best and last! Naturally, my hair is wavy/curly (depends on how I dry it).
1. Bumble and bumble - Hairdresser's Invisible Oil
This is a heat protectant, softening serum that's perfect for when you have ashy, white or silver hair and can't use Moroccan oil because of the brassiness. It makes your hair super soft and prevents little frizzies.
2. Redken - Powder Grip 03
This has changed my hair life. It's a powder that adds loads of volume and makes heavy, thick hair stay up! You can also use it go give your hair more life and absorb oil if you can't wash it. Powder a good amount into your hair while its at the end of being dry and make your hair messy, backcombed staying up or just more "volumized" (is that a word? I don't know.)
3. Joico - Power Spray
Best hairspray ever! I have a mini bottle and it's all I need! Really keeps your hair in place and the most you put on, the harder your hair gets, but you can't really even tell and you can still brush through it gently. Smells like bubblegum too, so that's a bonus!
4. PROLISS - Hair dryer
Really great.
5. Herbal Essences - Set Me Up Gel
Really great to always have gel just in case, and thankfully, I have this from my aunt and uncle when they came over! When my hair is dry, I massage a small dab of it in my hands, spread it through where I need it and blow dry it.
