Sally Hansen - Complete Care 7-in-1 Nail Treatment

Let's go through the '7 benefits'!
1. Base Coat (ok)
2. Top Coat (ok)
3. Growth (has calcium, so possible)
4. Strengthener (as a re-enforcement)
5. Ridge-Filler (all polish does this)
6. Brightener (no)

7. Ultra-Moisturising (It has avocado oil but no nail polish is 'ultra-moisturising'!)

But is isn't the worst list of claims I've seen.

As a top coat, it is pretty darn good.

Price: 1/5 ($19.95 for 13.3mL)
New Name: 5-in-1 Nail Treatment
Effectiveness: 4/5

Essie- Good To Go - Top Coat

Poor form, Essie!

But aside from that, it is a strong and super glossy top coat!

Revlon - Transforming Effects - Nail Enamel Top Coat - Matte Pearl Glaze 785

BYS - Glow In The Dark - Top Coat

This is a true glow-in-the-dark tops coat, not just a stupid polish that glows under a UV lamp.

Two coats, charged up under a lamp.

It is a pretty good top coat, but does mute the colour beneath it a little bit.

New Name: Bump In The Night

Avon - Opal - Top Coat

Art break - Thermochromatic Pen

When I was younger, I had a pen which looked black, but changed colour when it was heated up.
The ink itself was just normal ink, but the casing was thermochromatic.
Thermochromatic = changes colour in response to heat.

One way to do this is using liquid crystals (like in your LCD television).

I was reminded of this pen (long since lost in the folds of time) whilst watching SimplyNailogical's thermochromatic nails video.

I couldn't see why this couldn't be applied to a pen casing.

So I grabbed a pen and painted it in black acrylic paint.

I have a million of these pens!

Then I put on two thick layers of Solar Colour Dust liquid crystal paint. (They also sent me a sample of holographic glitter! <3)

Looks so unassuming!

Don't worry, it dries clear!

So far so good!

Finally, a sealing coat of top coat nail polish.

Verdict: I LOVE IT!

Sally Hansen - Insta-Dri Top Coat

I love Sally Hansen products, they are usually quite reliable.
This top coat was both good and bad. 
It was great to go over the top of my Revlon Gel Envy top coat (can you say overkill?) to get a great, professional finish (look).
It did dry quickly, but there in lies its downfall... because I could only use 3/4 of the bottle before it became gluggy and impossible to work with.
But that is the only negative, I love it otherwise and will probably repurchase it!

Price: 2/5(rrp $15.45 for 13.3mL)
Scent: 2/5 (not offensive beyond normal nail polish level)
Effectiveness: 4/5

Revlon - Colorstay Gel Envy - Diamond Top Coat

I live for this!

This is my favourite top coat of all time. Before this, I didn't like wearing nail polish because it would chip too fast (can't handle the chipping when I am out and can't fix it).

This top coat ensures I will get at least 5 days of nail perfection! (bear in mind, I'm a rough person who has a few tactile hobbies)

It is easy to apply with the doubled up brush, can be used with nail colours which are not in the 'Gel envy' range and dries pretty quickly.
And when you are ready to redo your nails, this is easy to remove with normal nail polish remover.

I must stock up on this so I don't run out for a long time, because I can't imagine a better top coat!

Price: 2/5 (rrp $16.95 for 11.7mL)
Scent: 2/5 (relatively non-offensive and mild for a nail polish, don't sniff nail polishes!)
Effectiveness: 5/5

Sally Hansen - Salon Effects - Real Nail Polish Strips - #410 Love Letter

I picked this up on sale and it looked like fun... nail polish stickers, how hard can it be? Right?!

When applying the stickers, the plastic was a bit fiddly to get off the nail polish part... I had about a 15% rip rate of the nail polish part.

Also, I had a few wrinkles in the end result, due to the distinct curvature of my nail not matching well with the planar nature of the sticker.

It looked good though!:

What I HATED though was that ONLY ONE DAY later it CHIPPED! I even had a top coat on! S.O.B!

I don't care if I have Shakespeare transcribed on my nails, if it's just going to chip within a day, I don't want it!

Solution:

This top coat is terrific! Use this on top if you insist on using the nail stickers. :)

Price: 2/5 (rrp $14.95 for one round)
Effectiveness: 2/5
