As far as I am concerned you can never ever have too much hair!! ...the worst thing is running out half way through your install -_- epic fail, but it happens time and time again! Please ladies always make sure you have enough hair prior to install so you are not running around like a scalped chicken trying to find more hair. Just because the minimum says two bundles for a full sewn in dont just buy two, get three instead. You will be pleasantly surprised when you are on two and a half or even the entire three bundles of hair towards the end of your sewn in.
Luckily for me I have never had that problem, but I have installed all the bundles I purchased and wanted my hair a little bit fuller, or a little bit longer. So for my next install which is coming up in the next few weeks or so, I bought a bundle of 26 inch and 28 inch. from DivaHairLLC, so all together I have six bundles of hair to install at my discretion. (for those of you who haven't read my post titled (Q&A on DivaHairLLC) here I went into greater detail on my purchase (of four bundles) and overall experience with the hair (minimal tangling and shedding) and the owner (Tamika B). I doubt if I can fit six bundles of hair on my itty bitty head but I am definitely going to install as much as possible.
On to the important part;
The Golden Glamour Girl's rule of thumb is the following:
I have finally realized that with shorter lengths the weft end of the bundles are fuller and with the longer lengths the weft end of the bundles (compartively) a little on the ligher side. Don't think that you are getting scammed out of an ounce or two, you are not! This may sound strange at first, because 4 ounces of hair should look like 4 ounces of hair no matter the length. BUT the longer lengths 20 and up are still 4 ounces, but you need to think about the difference in length causing a change in the amount of actually track (weft).
Longer hair (20 inch & above) weighs more (because of the length) so essentially you get a little less track (weft), same goes for short hair. Shorter hair (18 inch & below) weighs less so essentially you get more track (weft). _Either way you are still getting 4 ounces per bundle.
Once you understand this little detail, that I overlooked countless times, you'll know how much hair you need to achieve the desired fullness and length you like.
As far as how much you need I would follow the below guidelines, just to be on the safe side, I know other sites or stylists may tell you otherwise but this is from my own personal experience with bundles (ounces) of hair. Like I said before you usually hear people say buy two packs of hair and thats all you need. For as long I have been wearing weave (about 7 years) that has never ever been enough, and I mean never ever. I consider my head to be regular sized (I don't think I have a huge apple head), but my opinion may be a little bit biased. I usually use between 2 and 2 and 1/2 of the entire 3 bundles (this is for lengths 18 inch and below. I usually use between 3 and 1/2 to 4 bundles of hair when I install hair over 20 inches and above, but this is my first time installing 28 inch hair, so I will probably end up using almost 5 bundles! _either way I will keep you updated on that.
Just a quick reminder: I LOVE FULL HAIR!!!! so to me the MORE hair the BETTER :)
I am 5'5 and 24 inch Body Wave hits me about 2 inches above my butt when in its natural state.
