An expert explanation of how hair regrowth treatments work

There are so many products marketed toward hair loss, hair thinning and hair shedding, and while it can often be confusing to understand which ones are worth spending your money on, it’s important to know how they work.

So what exactly are hair regrowth treatments, what’s the science behind them and how can they be incorporated into your existing routine? We have the expert-led answers…

How do hair regrowth treatments work?

Hair regrowth treatments work to help reactivate hair follicles to stimulate regrowth. They are best for those who have general thinning of the hair on top of the scalp.

What is the science behind hair regrowth treatments?

These treatments can help to reverse hair loss by helping to kick-start inactive follicles. Upon application, they increase blood flow to the scalp and stimulate hair growth by cutting short the telogen phase of the hair growth cycle and extending the anagen phase.

The former is known as the rest phase and it lasts around three to four months and at the end, some hair falls out – losing around 100 strands a day is normal – and then new hair grows in its place.

The latter, anagen growth phase, is the one in which the hair follicle works to produce the hair fiber, leading to new strand growth. In short, it’s able to manipulate the natural cycle to encourage growth rather than shedding, and over time that means hair can grow back thicker and stronger.

Can hair regrowth treatments be used long term?

Put simply, yes. Trichologists recommend incorporating them into your routine long term to ensure you get the best results. Continuous use is needed to help maintain hair regrowth, and if you stop using it the hair loss process is likely to start again.

How experts recommend using hair growth treatments

For best results, apply up to twice a day to affected areas after washing, allowing it to remain there for at least four hours. It’ll take up to four months to see results, but stick with it – patience is key.

Using hair regrowth treatments alongside your other haircare

As far as the rest of your routine goes, experts recommend using a mild shampoo and conditioner that’ll be gentle on your hair – Nexxus Unbreakable Care range is great because it uses protein science to strengthen and support hair. It’s also best to try and limit your use of heat styling tools, and when you do use them, always remember to use a heat protector such as the Leave-In Lightweight Prep & Protect Spray beforehand to limit damage. Minimizing chemical coloring can also help your new strands grow long and strong.

Be sure to read all product descriptions before purchasing and labels before use to ensure product is used appropriately for desired result.
