Both Kiierr and Capillus are laser caps that are specially designed for hair loss problems faced by people.

They are both designated as medical grade since they come into touch with human bodies and support healthy hair development through noninvasive materials employed in their manufacture.

Both Kiierr and Capillus have been shown to help with baldness, fine hair, and loss of hair.

Both items come in the shape of a cap and employ low-level laser treatment.

As a result, there isn’t much of a difference in how they both work.

To encourage hair growth, red-light treatment or low-level laser therapy permits the cells to absorb the illuminating photons released into the scalp tissues.

According to the manufacturers of both caps, they claim that wearing this device on a daily basis promotes and feeds the cells in your hair strands.

It promotes thicker, healthier hair by thickening hair follicles.

Capillus laser cap come in 2 sizes in CapillusUltra, CapillusPlus, and CapillusPro that are regular and XL. the regular sizes of the caps are similar to size 7 of any ordinary hat and fit almost all the heads measuring up to 24” circumference.

While the XL sizes fit the people who wear hats size 8. Smaller hat sizes are within an effective range if the cap is within 2 cm (3/4″) all around.

As a result, while a regular Capillus cap may fit more snugly, anyone with a head circumference of 21″ or greater will be alright with it.

The same is the case with Kiier when comes to its sizes.

Working of these hair caps


Stimulates Skin Tissue – The lasers deliver a low-light treatment to the scalp’s skin tissue. As a result, blood flow is stimulated to the scalp tissue, which helps to reduce inflammation, and it begins to circulate throughout the head.The bloodstream supplies essential oxygen and nutrients to the hair follicles, resulting in cell regeneration in the hair’s damaged (diminishing) parts.

Protein Synthesis – When light energy reaches the skin, the weakened cells on the scalp absorb it. This stimulates the scalp and encourages the growth of new hair.

Regeneration of Hair Follicles – Recovers Hair Follicle Cells-Hair is “reborn” from the dormant (telogen) stage of the hair development cycle into the healthy growing (anagen) stage when hair follicle cells are recovered.


These low-level lasers are absorbed by hair follicles to stimulate hair activity by improving cell metabolism and renewing the follicles. It also boosts the number of active antigen hair follicles and their rate of proliferation.

Furthermore, there is evidence that the lasers increased gene activity.

It also reduces apoptosis by intracellularly targeting cytochrome C, which enhances blood vascularity.

Duration of Therapy

The therapy time recommended is 30 minutes every other day to get the desired results.

The therapy time shouldn’t exceed 6 minutes. The therapy should be repeated every other day.
