glam idol, Nikki Chantal!
So here’s the
thing, having a lot of hair is often referred to as having big hair… thick hair.  However, hair THICKNESS or coarseness, refers to the size of individual
strands, while having many (hundreds) of hair strands per square inch
refers to DENSITY. Therefore, it is possible to have densely packed fine
hair strands, in order words you can have “a whole lot” of fine hair
strands or not so densely packed thick strands 🙂
According to the
Science of Black Hair, “a strand of frayed thread is about the thickness
of a medium sized strand of hair. If your strand is larger than this,
then your hair is thick, if your strand is smaller than this, your hair
is fine.”
For the most
part, the thickness and density of your hair is determined by genetics and hormones.  It is said that having large follicles yields larger strands and vice
versa. So unfortunately, if you were not born with thick/coarse strands, then it is unlikely that there is anything that you can do to “make your strands thicker.” However, hair that was once quite dense but thinned due to
medication, hormonal issues, chemical treatments or hair color does have
the ability to be “re-thickened”, so to speak. 
For the purposes of this article, we’re going to discuss ways to
potentially thicken up the strands you already have to create the
illusion of bigger hair, as genetics already determined how many
follicles you were gifted. 

  • Hair is made
    up of protein and a break down of the protein structure will cause hair
    to thin. Incorporating more protein into one’s diet as well as adding strengthening protein products (hydrolyzed protein) to your hair will help to fill in any
    gaps/spaces that may be in the hair shaft, causing it to appear thicker.
    *Don’t overdo the protein
    products though because if your hair is not sufficiently “soft AND
    strong” (protein-moisture balance) you will end up with a whole other
    set of problems*
  • Henna/Cassia
    – These both mimic protein treatments and coat the hair shaft, causing
    the hair strand to appear thicker. Both of these treatments (especially henna) may loosen
    your curl pattern overtime, so it’s important to take steps (adding Amla
    powder, spacing treatments and/or doing just your roots) to prevent this if it’s not a desired
    effect. I know this works because I used henna/cassia treatments to
    re-thicken areas of my hair that thinned a bit due to medication.  
  • Styling on dry hair – this is a great option for allowing your hair to appear fuller.
  • Applying Castor oil
    – as you know Castor oil is always the suggestion when someone asks
    “what can I do to thicken my hair.” I know for a fact it works on hair
    that was once thick since I’ve used to re-thicken my edges. However, I
    do not know for sure if it works on “genetically” fine hair. The theory
    behind Castor oil is that “when rubbed on
    the scalp, castor oil has restorative properties that not only keep the
    scalp moisturized, but also help thin hair grow thicker and keep hair
    from falling out.
    The Omega-9 fatty acids in castor oil helps to regenerate new hair growth within just a few months.” Source 
only issue with these “solutions” is that they are temporary so they
need to be constantly repeated in order to maintain the benefits.

Henna works to build up my puny strands.  My strands go from wispy/see-through, to baby doll strands (coarser, fortified and shiny as hell) after a few treatments.  If you decide to embark on a henna journey do your research first!  Styling on dry hair is another trick I lean on in the cooler months.  Works like a charm!  Share your tips below!
