Sure! First of all, if you don't have Photoshop and use Paint Tool Sai or something else, I don't know how you can do thisBut I think reading it will still be helpful in understanding the method and trying to figure out different ways in other programs.I watched this tutorial and downloaded his brushes (I used 2 different brushes to draw these but mainly his one) - www.youtube.com/watch?v=-fbRQc… 1) Create a silhouette, basically it's just a block of colour in the shape of the hair you want. Lower the opacity of it2) Use the brush you downloaded and decide on a where the hair parting is. Start painting over the top and make sure the hair's direction is consistent (this may be very confusing cause it was extremely confusing for me at the start, I always painted like 5 strokes and stopped cause I thought it looked really bad, but just keep going at it, you will start to see a flow and shape forming). For now, stay on one colour and make sure to vary the size of the brush so you get different sized hair.3) Once you have hair that flows nicely and in the correct diretions, pick different shades of shadows and just put them in where they will appear by painting repeatedly on top with the same brush. This was explained in the tutorial but I will say it once again here since it's extremely simple but effective - choose a really dark shade of the hair and use a simple pen tool to draw in singular lines. This is kind of hard to explain without me actually doing it, but for example, in the hair I drew in the bottom right, you can see random glowy yellows at the end of the hair which makes it pop. Once you're done drawing in random lines, lower the opacity if it's too dark.4) Basically do the same as step 3, but with different highlight colours. Make sure you do the simple and effective trick with a pen tool where you draw singular lines and play with the opacity settings.5) [OPTIONAL STEP] Add a backlight, if you don't know what this is, it's just a light that comes from behind or somewhere else apart from the main highlight of the picture. If you look closely, my hairs have random blue and green colours at the end of the hair. This makes the hair pop out even more, but it can also be a bad effect if used incorrectly so be careful with it.6) [OPTIONAL STEP but definitely recommended] Once again, this was done in the tutorial, grab an airbrush and choose black as the colour. Lightly brush over the shadows/dark spots. Once done, play with the opacity settings of the layer. Do the same with a white colour but use it on highlights only.And that's pretty much it I think! Watching JesusConde's tutorial really showed me how to use opacity on layers correctly. You could even use put complete black on top of anything, lower the opacity of the layer and it will turn out really effective. Make sure every change you do is on a different layer because you can easily mess up the hair and you can easily fix it by deleting the layer. Sorry for the massive reply but I don't think I could of made it any shorter! This may seem EXTREMELY confusing, but trust me you'll get there. Believe it or not hair was literally my most hated thing to draw, sometimes I would even avoid drawing it... But now I love drawing hair! Now I mainly need to work on my hands...
