Eyebrow growth can slow for a number of reasons, resulting in eyebrows which are thin and sparse. Sun exposure is a major factor; UV exposure can cause keratin and other protein bonds to break. This makes the hair brittle and prone to breakage.
Over-plucking can also cause damage to your brows, and conditions like hyperthyroidism can affect growth towards the edge of the browline.
In all of these cases, a product like Opti Laboratories Brow Growth Treatment can help to thicken and darken remaining hairs. It can also thicken, lengthen and darken the pale delicate hairs around the browline, for a fuller effect. Opti Laboratories Growth Treatment has been clinically proven to impact hair growth and is safe to apply to the brow area.
Our world-first Opti Laboratories Sun Protect Serum can also be applied to brows to protect new growth from sun damage for optimum condition.
Opti Laboratories Growth Treatment can be used on both the lashes and brows.
It contains a 0.3 mg/ml (0.03%) solution of bimatoprost, a prostaglandin analogue, the exact same as Latisse. Bimatoprost mimics a naturally-occurring molecule, which regulates the growth of your hair.
When you apply bimatoprost to the base of a hair, it soaks into the hair follicle and causes the hair to enter its anagen, or growth phase. The individual hairs grow thicker and longer than normal. The increased thickness often results in a darker appearance to each hair.
When applied to vellus hairs the treatment thickens and darkens them enough to make them appear like “proper” hairs. Vellus hairs are the tiny hairs found all over the body except the palms of your hands and the soles of your feet. This is sufficient to thicken an over-plucked or thinning brow.
The FDA trial in America for the approval of bimatoprost for cosmetic use found that the eyelashes on which it was tested were on average 106% thicker, 25% longer and 18% darker than before.
Research has shown that the treatment works just as effectively on eyebrows as it does on eyelashes. The specific % increases in length, thickness and colour saturation, however, have not been formally measured.
Most lash treatment users see results within 4 weeks, but best results take 16 weeks to appear. This is because the growth cycle for each of your individual hairs takes 16 weeks on average to complete.
In our experience we have found that eyebrow hairs tend to grow faster than eyelashes. We expect that you’ll notice your first results in 4 weeks, and full results in 12-14 weeks.
Opti Laboratories Growth Treatment can be provided with a purposely designed precision applicator to ensure you get the best results.

"I’ve been using the treatment lotion from Opti Labs for a year now. My lashes are so much fuller I no longer wear mascara. I’ve also been using the lotion on my eyebrows which became thinner after I was diagnosed with a low functioning thyroid and they are so much improved. I can’t imagine ever stopping - perish the thought!"
