I am so glad you asked because I have fine, 3b/3c curly hair and A LOT OF IT, and my whole life I have struggled to find products & a routine that define my curls but still give me volume without weighing my hair down or making it greasy! preface: this is a long one! But please read through everything, I promise it will change your life like it did mine!!
Judging by your profile picture, it seems like you may also have fine(ish)/medium thick hair? similar to mine. please bear in mind that hair type & thickness is a massive factor in how well certain products Will work. But I don’t think a serum is gonna be enough to get your curls defined & frizz-free /: the gels and creams youve tried may also be too thick!
My holy grail products:
*curlsmith weightless air dry cream (leave-in)
*innersense hair love prep spray (basically another leave in but in liquid form)
*curlsmith hold me softly style balm (actual styling cream)
*any type of *lightweight* oil or thermal protectant spray - I alternate between argan oil, joico’s k-pak color therapy oil, and Kenra’s platinum blow dry smell (smells sooo good)
^these products are very lightweight but work great together in holding your curls so that you can easily go days in between washing and styling.
Now the key is not only which products you use but how much of each product you’re using! This is important bc if you use too much of a product, especially one that is heavy, it’s going to weigh your hair down, making it greasy & limp - even still for lightweight products. so measuring the amount of product to use is key & here’s how to do it: start by parting your hair like you normally would and then bring the hair on either side of your part around to the front. then take your index finger & thumb and wrap your fingers around each section of hair shafts (WHILE WET). when your hair fits snug into whatever shape and size ring you’ve created with your fingers, bring your fingers down through the section of hair being sure not to break your fingers up, keeping the ring of ur index finger & thumb, and whatever shape/size your left with is the exact amount of product youre gonna want to disperse through your hair. you’ll use that same amount for every product you use, except for the oil at the end.
Actual routine:
With hair soaking wet, BEFORE brushing, I apply my leave-in to each section. Then go ahead and spritz each section with the prep love spray. mind you, the sections are just the hair on either side of my part - so two sections all together, basically both halves of my hair. after a few spritzes on either section, I then go in with a brush (any type of detangling brush is fine, idek which one I use, it’s from Amazon) and brush out all the tangles. Brushing after applying these products ensures that it all gets dispersed evenly. then, re-section your hair and go in with your styling cream, raking it evenly thru the hair. Now 2nd to last step is KEY. The denman brush (which u can get on Amazon) is whats really gonna ensure your curls are defined. Prior to this step tho, make sure your hair is still wet, or at least 85% wet. If it’s not, spritz it with some water bc brushing through dry hair of any degree is going to create frizz! What you do w the denman brush is essentially break up your hair into more, smaller, sections, and brush through each section with the denman brush. This can be time consuming at first but the more you do it, the quicker you get w it. I don’t bother to create a bunch of sections anymore - I just clip all of my hair up leaving the bottom layer out and kind of repeat that process, working my way up to the crown & front pieces. but the key is making sure that each section is small. once you’ve passed through each section w the denman brush, you can go in with a TINY amount of oil. then diffuse!!! you can also air dry but I find diffusing to make my curls look nicer.
I know that was a lot but it’s really quite simple when you put it into practice. Hope this helps! 🤍
